+
+ncpfs-2.0.5 -> ncpfs-2.0.6
+- Added a short description of a problem that I need help with to the
+  file BUGS. If you know a bit of the linux networking code, please
+  take a look at it. Thanks a lot.
+- Added canonic output format to nwpbvalues and the command nwbpset. I
+  would like to invite you to help building capable bindery management

FAQ

@@ -0,0 +1,67 @@
+There is certainly not enough material to call this an FAQ, but some
+questions reach me regularly. Probably the documentation is not clear
+enough.
+
+-------------------------------------------------------------------------------
+
+Q: The ncpfs utilities like slist or ncpmount tell me that they can
+   not find a server, although I'm sure there are servers on my
+   net. What's wrong?
+
+You probably used 
+
+ipx_configure --auto_interface=on --auto_primary=on 
+
+and you have Windows (95?) workstations on your network. Windows 95
+makes Linux configure IPX interfaces for non-existent frame types. To
+solve this problem, you have to configure your IPX interface manually
+with the command
+
+ipx_interface add -p <device> <frame>
+
+For <device> use eth0, eth1 or whatever you network adapter is
+called. The value for <frame> must match the frame type used on your
+network. Possible values are 802.2, 802.3, SNAP and EtherII.
+
+-------------------------------------------------------------------------------
+
+Q: I have difficulties with NetWare 4.1. What can I do?
+
+To be honest, I do not really know. Currently my only test equipment
+is a NetWare 3.11 server. You should make your 4.1 Server as
+3.x-compatible as it can be. As I do not know 4.1, you are on your own
+doing this.
+
+A promising hint that has already helped some people is to switch off
+packet signatures on the 4.1 server, as ncpfs does not support them.
+
+-------------------------------------------------------------------------------
+
+Q: When I re-export ncpfs-mounted directories via nfs, I get messages like
+   'pwd: cannot get current directory', and other strange things happen to
+   the nfs clients. What's wrong?
+
+When you want to export a directory via NFS, you have to do two things:
+
+- You have to invoke mountd and nfsd with the option --re-export. On my
+  computer, both are invoked at system startup from the file
+  /etc/rc.d/rc.inet2.
+
+- You can not export a complete NetWare server hierarchy with all volumes
+  under a single mount point. You have to mount a single server volume to
+  make it re-exportable. Invoke ncpmount with the option -V volume to do
+  this.
+
+-------------------------------------------------------------------------------
+
+Q: When I compile ncpfs, I get a message like the following:
+
+make[1]: Entering directory `/home/me/netware/ncpfs/kernel-1.2/src'
+gcc -D__KERNEL__ -I. -Wall -Wstrict-prototypes -O2 -DMODULE -fomit-frame-pointer -I/home/me/netware/ncpfs/kernel-1.2 -DNCPFS_VERSION=\"0.17\"  -c dir.c

-This is version 0.8 of ncpfs, a free NetWare client filesystem for

-whether it works with any other kernel of the 1.2.x series, I only
-used it with 1.2.13.
+This is ncpfs, a free NetWare client filesystem for Linux. Besides
+some little utilities it also contains nprint, which enables you to
+print on NetWare print queues. The opposite side, pserver, is also
+provided.
 
-Due to problems in the 1.3.x IPX kernel code, ncpfs-0.8 does NOT work
-with any 1.3.x kernel up to 1.3.45, although there is a kernel-1.3
-subdirectory. It compiles fine and seems to work, but any connection
-will block after a very short time. Please be patient. I'm sure this
-will be solved. If you follow the kernel development closely, you
-might want to try ncpfs with a kernel later than 1.3.45, but I can not
-promise anything. To try it with 1.3, simply change the variable
-KERNEL in the Makefile from 1.2 to 1.3 and continue as usual.
+ncpfs works with NetWare versions 3.x and following. It does NOT work
+with NetWare version 2.x. Some of the NetWare look-alikes, such as
+CD-ROM servers WinNT 3.51 Server are also NOT supported. This
+restriction comes from the fact that ncpfs relies heavily on the name
+space facilities NetWare supports since version 3. When you want to
+mount volumes that have been exported by mars_nwe, you have to
+activate the name space calls in mars_nwe's config.h file, although
+probably it's more clever to use nfs between two Linux machines.
 
-To install ncpfs, just type 'make'. After that, you find the
-neccessary kernel module and the mounting tools in ./bin. Type 'insmod
-ncpfs.o' and then 'ncpmount server mount-point'. For further
-information, please look at the manual pages in ./man.
+The user-space utilities such as nprint and the bindery utils should
+work with all versions of NetWare.
+
+ncpfs does NOT support access to the NDS, so if you want to mount
+volumes exported by a NetWare 4.x server, you will have to install the
+bindery emulation on that server. If you need access to the NDS, ask
+Caldera for their CND. See http://www.caldera.com for more
+information.
+
+
+INSTALLATION
+
+Before you start the installation, make sure that your kernel has IPX
+support compiled in. When 'make config' asks you for
+
+The IPX protocol (CONFIG_IPX) [N/y/m/?]
+
+simply answer 'y'. Probably you do not need the full internal net that
+you are asked for next.
+
+The installation of ncpfs depends on the kernel version you are
+using. For kernel 1.2, you should simply type 'make' and look at
+what's in the bin/ directory after that. Please be sure that your
+kernel resides in /usr/src/linux, because the file
+kernel-1.2/src/sock.c has to refer directly to it.
+
+If you use Kernel 1.3, please be sure that you use at least
+1.3.71. ncpfs does NOT work with any earlier 1.3.x kernel.
+
+If you use Kernel 1.3.71 or later, you might have to recompile your
+kernel. With these kernels, the kernel part of ncpfs is already
+included in the main source tree. If you want to use ncpfs, you should
+say 'y' to 'make config' when you are asked for IPX, and again when it
+asks for ncpfs. After you have rebooted with the new kernel, 'cat
+/proc/filesystems' should show you a line saying that the kernel knows
+ncpfs.
+
+If you are running kerneld, please uncomment the corresponding line in
+the Makefile to reflect this.
+
+If your system is ELF, please enable the use of the shared ncp-library
+in the Makefile. This will save at least 1MB of disk space.
+
+After you adapted your Makefile, type 'make' and, as root, 'make install'.

-The second limitation is just as annoying as the first: You cannot
-re-export a ncp-mounted directory by nfs. It is not possible because
-the NFS protocol defines access to files through unique file handles,
-which can be mapped to the device and inode numbers in unix NFS
-servers. NCP does not have unique numbers per file, you only have the
-path name. I implemented a caching scheme for inode numbers, which
-gives unique inode numbers for every open file in the system. This is
-just sufficient for local use of the files, because you can tell when
-an inode number can be discarded. With NFS the situation is
-different. You can never know when the client will access the file-id
-you offered, so you would have to cache the inode numbers

+Tknwmsg 1.0 for NCPFS. 
+
+Kevin Burton (kburto1@umbc.edu), Copyright 1996
+Distributed under GPL (GNU Public License)
+
+-- INTRO --
+
+Tknwmesg is a extension for ncpfs for linux that allows users to recived messages
+while under an X console.  
+
+Essentially it is an extension for nwmsg that comes with ncpfs.  The only 
+changes are a system() call to a tk script that will run a dialog with an "ok"
+button under X.
+
+--  INSTALLATION --
+TCL/TK must be installed on your system.  If they are not then you will have to
+get the source for their installation if you want to run tkmesg.  
+
+	-  Download ncpfs from sunsite.unc.edu
+	-  Run "su" to become root if you are not already root.
+	-  Unpack ncpfs in a temporary directory.
+	-  copy the Tknwmsg nwmsg.c to util/nwmsg.c in your ncpfs directory.
+	-  copy tknwmsg to /usr/bin
+	-  change to your nwmsg directory.
+	-  run "make all;make install" and the new version of tknwmsg will be 
+	   installed.
+	  
+--  USE --
+
+	- At least 1 terminal on the local system must be have "mesg y".  Else
+	  no GUI dialog will be displayed.
+          
+          Using mesg y in a .bashrc will not work.  The only way that I have 
+	  found to do this is to have chmod a+w /dev/ttyp? in Xsession or 
+   	  $HOME/.xsession.  Also it may be necessary to have .bashrc do the
+	  same thing if users are starting and stopping xterms.

+This is a VERY stupid packet sniffer for IPX ethernet packets.
+
+ =============================================

+ =============================================
+
+If you are using unencrypted passwords, and use this tool to send a
+dump to somebody else or store it on a computer, you might very well
+store passwords there. So, be VERY careful! This is exactly the kind
+of tools Novell designed the encrypted passwords for (or against).
+
+
+
+I hacked it together to be able to help people with problems with
+ncpfs. The socket handling was taken from Statnet-2.0.
+
+You can use it to watch commercial NetWare clients when they talk to
+servers. I divided the program into 2 parts, ipxdump and ipxparse.
+
+ipxdump simply pumps all the IPX frames it receives to stdout.
+
+If you use ipxdump to watch a workstation, you can use the simple
+filter function ipxdump provides. You can call ipxdump with the node
+address of the workstation you want to watch. This way only the
+packets this workstation sends and receives are monitored. As an
+example, I call ipxdump as
+
+  ./ipxdump 00001B038B11
+
+to look at my 286/10MHz test 'workstation'. ipxdump still generates
+huge amounts of data, so you should be very careful to start it just
+before you perform the operation (such as file creation for OS/2
+clients with NW4.1 as a server, or a 'dir' on a directory with long
+and short file names, or an encrypted password change ;-)) and stop it
+directly after that. And, please gzip -9 and uuencode it before you
+send it to anybody.
+
+ipxparse will eventually take apart the dump that ipxdump
+generates. They can as well be used in a pipe. Currently ipxparse does
+not do anything sensible, but that will definitely change.

+composed of the
+.I whoami
+string, which should specify the program name or some subportion of
+a program, followed by an error message generated from the
+.I code
+value (derived from
+.IR compile_et (1)),
+and a string produced using the

+string and any following arguments, in the same style as

+
+The behavior of
+.I com_err
+can be modified using
+.I set_com_err_hook;
+this defines a procedure which is called with the arguments passed to

+instead of the default internal procedure which sends the formatted
+text to error output.  Thus the error messages from a program can all
+easily be diverted to another form of diagnostic logging, such as
+.IR syslog (3).
+.I Reset_com_err_hook
+may be used to restore the behavior of
+.I com_err
+to its default form.  Both procedures return the previous ``hook''
+value.  These ``hook'' procedures must have the declaration given for
+.I proc
+above in the synopsis.
+
+The
+.I initialize_XXXX_error_table
+routine is generated mechanically by
+.IR compile_et (1)
+from a source file containing names and associated strings.  Each
+table has a name of up to four characters, which is used in place of
+the
+.B XXXX
+in the name of the routine.  These routines should be called before
+any of the corresponding error codes are used, so that the
+.I com_err
+library will recognize error codes from these tables when they are
+used.
+
+The
+.B com_err.h
+header file should be included in any source file that uses routines
+from the
+.I com_err
+library; executable files must be linked using
+.I ``-lcom_err''
+in order to cause the
+.I com_err
+library to be included.

+
+UNIX has always had a clean and simple system call interface, with a
+standard set of error codes passed between the kernel and user
+programs.  Unfortunately, the same cannot be said of many of the
+libraries layered on top of the primitives provided by the kernel.
+Typically, each one has used a different style of indicating errors to
+their callers, leading to a total hodgepodge of error handling, and
+considerable amounts of work for the programmer.  This paper describes
+a library and associated utilities which allows a more uniform way for
+libraries to return errors to their callers, and for programs to
+describe errors and exceptional conditions to their users.

+@section Why com_err?
+
+In building application software packages, a programmer often has to
+deal with a number of libraries, each of which can use a different
+error-reporting mechanism.  Sometimes one of two values is returned,
+indicating simply SUCCESS or FAILURE, with no description of errors
+encountered.  Sometimes it is an index into a table of text strings,
+where the name of the table used is dependent on the library being
+used when the error is generated; since each table starts numbering at
+0 or 1, additional information as to the source of the error code is
+needed to determine which table to look at.  Sometimes no text messages are
+supplied at all, and the programmer must supply them at any point at which
+he may wish to report error conditions.
+Often, a global variable is assigned some value describing the error, but
+the programmer has to know in each case whether to look at @code{errno},
+@code{h_errno}, the return value from @code{hes_err()}, or whatever other
+variables or routines are specified.
+And what happens if something
+in the procedure of
+examining or reporting the error changes the same variable?
+
+The package we have developed is an attempt to present a common
+error-handling mechanism to manipulate the most common form of error code
+in a fashion that does not have the problems listed above.
+
+A list of up to 256 text messages is supplied to a translator we have
+written, along with the three- to four-character ``name'' of the error
+table.  The library using this error table need only call a routine
+generated from this error-table source to make the table ``known'' to the
+com_err library, and any error code the library generates can be converted
+to the corresponding error message.  There is also a default format for
+error codes accidentally returned before making the table known, which is
+of the form @samp{unknown code foo 32}, where @samp{foo} would be the name
+of the table.
+
+@section Error codes
+
+Error codes themselves are 32 bit (signed) integers, of which the high
+order 24 bits are an identifier of which error table the error code is
+from, and the low order 8 bits are a sequential error number within
+the table.  An error code may thus be easily decomposed into its component
+parts.  Only the lowest 32 bits of an error code are considered significant
+on systems which support wider values.
+
+Error table 0 is defined to match the UNIX system call error table
+(@code{sys_errlist}); this allows @code{errno} values to be used directly
+in the library (assuming that @code{errno} is of a type with the same width
+as @t{long}).  Other error table numbers are formed by compacting together
+the first four characters of the error table name.  The mapping between
+characters in the name and numeric values in the error code are defined in
+a system-independent fashion, so that two systems that can pass integral
+values between them can reliably pass error codes without loss of meaning;
+this should work even if the character sets used are not the same.
+(However, if this is to be done, error table 0 should be avoided, since the
+local system call error tables may differ.)
+
+Any variable which is to contain an error code should be declared @t{long}.
+The draft proposed American National Standard for C (as of May, 1988)
+requires that @t{long} variables be at least 32 bits; any system which does
+not support 32-bit @t{long} values cannot make use of this package (nor
+much other software that assumes an ANSI-C environment base) without
+significant effort.
+
+@section Error table source file
+
+The error table source file begins with the declaration of the table name,
+as
+
+@example
+error_table @var{tablename}
+@end example
+
+Individual error codes are
+specified with
+
+@example
+error_code @var{ERROR_NAME}, @var{"text message"}
+@end example
+
+where @samp{ec} can also be used as a short form of @samp{error_code}.  To
+indicate the end of the table, use @samp{end}.  Thus, a (short) sample
+error table might be:
+
+@example
+
+        error_table     dsc
+
+        error_code      DSC_DUP_MTG_NAME,
+                        "Meeting already exists"
+
+        ec              DSC_BAD_PATH,
+                        "A bad meeting pathname was given"
+
+        ec              DSC_BAD_MODES,
+                        "Invalid mode for this access control list"
+
+        end
+
+@end example
+
+@section The error-table compiler
+
+The error table compiler is named @code{compile_et}.  It takes one
+argument, the pathname of a file (ending in @samp{.et}, e.g.,
+@samp{dsc_err.et}) containing an error table source file.  It parses the
+error table, and generates two output files -- a C header file
+(@samp{discuss_err.h}) which contains definitions of the numerical values
+of the error codes defined in the error table, and a C source file which
+should be compiled and linked with the executable.  The header file must be
+included in the source of a module which wishes to reference the error
+codes defined; the object module generated from the C code may be linked in
+to a program which wishes to use the printed forms of the error codes.
+
+This translator accepts a @kbd{-language @var{lang}} argument, which
+determines for which language (or language variant) the output should be
+written.  At the moment, @var{lang} is currently limited to @kbd{ANSI-C}
+and @kbd{K&R-C}, and some abbreviated forms of each.  Eventually, this will
+be extended to include some support for C++.  The default is currently
+@kbd{K&R-C}, though the generated sources will have ANSI-C code
+conditionalized on the symbol @t{__STDC__}.
+
+@section Run-time support routines
+
+Any source file which uses the routines supplied with or produced by the
+com_err package should include the header file @file{<com_err.h>}.  It
+contains declarations and definitions which may be needed on some systems.
+(Some functions cannot be referenced properly without the return type
+declarations in this file.  Some functions may work properly on most
+architectures even without the header file, but relying on this is not
+recommended.)
+
+The run-time support routines and variables provided via this package
+include the following:
+
+@example
+void initialize_@var{xxxx}_error_table (void);
+@end example
+
+One of these routines is built by the error compiler for each error table.
+It makes the @var{xxxx} error table ``known'' to the error reporting
+system.  By convention, this routine should be called in the initialization
+routine of the @var{xxxx} library.  If the library has no initialization
+routine, some combination of routines which form the core of the library
+should ensure that this routine is called.  It is not advised to leave it
+the caller to make this call.
+
+There is no harm in calling this routine more than once.
+
+@example
+#define ERROR_TABLE_BASE_@var{xxxx} @var{nnnnn}L
+@end example
+
+This symbol contains the value of the first error code entry in the
+specified table.
+This rarely needs be used by the
+programmer.
+
+@example
+const char *error_message (long code);
+@end example
+
+This routine returns the character string error message associated
+with @code{code}; if this is associated with an unknown error table, or
+if the code is associated with a known error table but the code is not
+in the table, a string of the form @samp{Unknown code @var{xxxx nn}} is
+returned, where @var{xxxx} is the error table name produced by
+reversing the compaction performed on the error table number implied
+by that error code, and @var{nn} is the offset from that base value.
+
+Although this routine is available for use when needed, its use should be
+left to circumstances which render @code{com_err} (below) unusable.
+
+@example
+void com_err (const char *whoami,  /* module reporting error */
+              long code,           /* error code */
+              const char *format,  /* format for additional detail */
+              ...);                /*  (extra parameters) */
+@end example
+
+This routine provides an alternate way to print error messages to
+standard error; it allows the error message to be passed in as a
+parameter, rather than in an external variable.  @emph{Provide grammatical
+context for ``message.''}
+
+If @var{format} is @code{(char *)NULL}, the formatted message will not be
+printed.  @var{format} may not be omitted.
+
+@example
+#include <stdarg.h>
+
+void com_err_va (const char *whoami,
+                 long code,
+                 const char *format,
+                 va_list args);
+@end example
+
+This routine provides an interface, equivalent to @code{com_err} above,
+which may be used by higher-level variadic functions (functions which
+accept variable numbers of arguments).
+
+@example
+#include <stdarg.h>
+
+void (*set_com_err_hook (void (*proc) ())) ();
+
+void (*@var{proc}) (const char *whoami, long code, va_list args);
+
+void reset_com_err_hook ();
+@end example
+
+These two routines allow a routine to be dynamically substituted for
+@samp{com_err}.  After @samp{set_com_err_hook} has been called,
+calls to @samp{com_err} will turn into calls to the new hook routine.
+@samp{reset_com_err_hook} turns off this hook.  This may intended to
+be used in daemons (to use a routine which calls @var{syslog(3)}), or
+in a window system application (which could pop up a dialogue box).
+
+If a program is to be used in an environment in which simply printing
+messages to the @code{stderr} stream would be inappropriate (such as in a
+daemon program which runs without a terminal attached),
+@code{set_com_err_hook} may be used to redirect output from @code{com_err}.
+The following is an example of an error handler which uses @var{syslog(3)}
+as supplied in BSD 4.3:
+
+@example
+#include <stdio.h>
+#include <stdarg.h>
+#include <syslog.h>
+
+/* extern openlog (const char * name, int logopt, int facility); */
+/* extern syslog (int priority, char * message, ...); */
+
+void hook (const char * whoami, long code,
+           const char * format, va_list args)
+@{
+    char buffer[BUFSIZ];
+    static int initialized = 0;
+    if (!initialized) @{
+        openlog (whoami,
+                 LOG_NOWAIT|LOG_CONS|LOG_PID|LOG_NDELAY,
+                 LOG_DAEMON);
+        initialized = 1;
+    @}
+    vsprintf (buffer, format, args);
+    syslog (LOG_ERR, "%s %s", error_message (code), buffer);
+@}
+@end example
+
+After making the call
+@code{set_com_err_hook (hook);},
+any calls to @code{com_err} will result in messages being sent to the
+@var{syslogd} daemon for logging.
+The name of the program, @samp{whoami}, is supplied to the
+@samp{openlog()} call, and the message is formatted into a buffer and
+passed to @code{syslog}.
+
+Note that since the extra arguments to @code{com_err} are passed by
+reference via the @code{va_list} value @code{args}, the hook routine may
+place any form of interpretation on them, including ignoring them.  For
+consistency, @code{printf}-style interpretation is suggested, via
+@code{vsprintf} (or @code{_doprnt} on BSD systems without full support for
+the ANSI C library).
+
+@section Coding Conventions
+
+The following conventions are just some general stylistic conventions
+to follow when writing robust libraries and programs.  Conventions
+similar to this are generally followed inside the UNIX kernel and most
+routines in the Multics operating system.  In general, a routine
+either succeeds (returning a zero error code, and doing some side
+effects in the process), or it fails, doing minimal side effects; in
+any event, any invariant which the library assumes must be maintained.
+
+In general, it is not in the domain of non user-interface library
+routines to write error messages to the user's terminal, or halt the
+process.  Such forms of ``error handling'' should be reserved for
+failures of internal invariants and consistancy checks only, as it
+provides the user of the library no way to clean up for himself in the
+event of total failure.
+
+Library routines which can fail should be set up to return an error
+code.  This should usually be done as the return value of the
+function; if this is not acceptable, the routine should return a
+``null'' value, and put the error code into a parameter passed by
+reference.
+
+Routines which use the first style of interface can be used from
+user-interface levels of a program as follows:
+
+@example
+@{
+    if ((code = initialize_world(getuid(), random())) != 0) @{
+        com_err("demo", code,
+                "when trying to initialize world");
+        exit(1);
+    @}
+    if ((database = open_database("my_secrets", &code))==NULL) @{
+        com_err("demo", code,
+                "while opening my_secrets");
+        exit(1);
+    @}
+@}
+@end example
+
+A caller which fails to check the return status is in error.  It is
+possible to look for code which ignores error returns by using lint;
+look for error messages of the form ``foobar returns value which is
+sometimes ignored'' or ``foobar returns value which is always
+ignored.''
+
+Since libraries may be built out of other libraries, it is often necessary
+for the success of one routine to depend on another.  When a lower level
+routine returns an error code, the middle level routine has a few possible
+options.  It can simply return the error code to its caller after doing
+some form of cleanup, it can substitute one of its own, or it can take
+corrective action of its own and continue normally.  For instance, a
+library routine which makes a ``connect'' system call to make a network
+connection may reflect the system error code @code{ECONNREFUSED}
+(Connection refused) to its caller, or it may return a ``server not
+available, try again later,'' or it may try a different server.
+
+Cleanup which is typically necessary may include, but not be limited
+to, freeing allocated memory which will not be needed any more,
+unlocking concurrancy locks, dropping reference counts, closing file
+descriptors, or otherwise undoing anything which the procedure did up
+to this point.  When there are a lot of things which can go wrong, it
+is generally good to write one block of error-handling code which is
+branched to, using a goto, in the event of failure.  A common source
+of errors in UNIX programs is failing to close file descriptors on
+error returns; this leaves a number of ``zombied'' file descriptors
+open, which eventually causes the process to run out of file
+descriptors and fall over.
+
+@example
+@{
+    FILE *f1=NULL, *f2=NULL, *f3=NULL;
+    int status = 0;
+
+    if ( (f1 = fopen(FILE1, "r")) == NULL) @{
+        status = errno;
+        goto error;
+    @}
+
+    /*
+     * Crunch for a while
+     */
+
+    if ( (f2 = fopen(FILE2, "w")) == NULL) @{
+        status = errno;
+        goto error;
+    @}
+
+    if ( (f3 = fopen(FILE3, "a+")) == NULL) @{
+        status = errno;
+            goto error;
+    @}
+
+    /*
+     * Do more processing.
+     */
+    fclose(f1);
+    fclose(f2);

+
+@section Building and Installation
+
+The distribution of this package will probably be done as a compressed
+``tar''-format file available via anonymous FTP from SIPB.MIT.EDU.
+Retrieve @samp{pub/com_err.tar.Z} and extract the contents.  A subdirectory
+@t{profiled} should be created to hold objects compiled for profiling.
+Running ``make all'' should then be sufficient to build the library and
+error-table compiler.  The files @samp{libcom_err.a},
+@samp{libcom_err_p.a}, @samp{com_err.h}, and @samp{compile_et} should be
+installed for use; @samp{com_err.3} and @samp{compile_et.1} can also be
+installed as manual pages.
+
+Potential problems:
+
+@itemize @bullet
+
+@item Use of @code{strcasecmp}, a routine provided in BSD for
+case-insensitive string comparisons.  If an equivalent routine is
+available, you can modify @code{CFLAGS} in the makefile to define
+@code{strcasecmp} to the name of that routine.
+
+@item Compilers that defined @code{__STDC__} without providing the header
+file @code{<stdarg.h>}.  One such example is Metaware's High ``C''
+compiler, as provided at Project Athena on the IBM RT/PC workstation; if
+@code{__HIGHC__} is defined, it is assumed that @code{<stdarg.h>} is not
+available, and therefore @code{<varargs.h>} must be used.  If the symbol
+@code{VARARGS} is defined (e.g., in the makefile), @code{<varargs.h>} will
+be used.
+
+@item If your linker rejects symbols that are simultaneously defined in two
+library files, edit @samp{Makefile} to remove @samp{perror.c} from the
+library.  This file contains a version of @var{perror(3)} which calls
+@code{com_err} instead of calling @code{write} directly.
+
+@end itemize
+
+As I do not have access to non-BSD systems, there are probably
+bugs present that may interfere with building or using this package on
+other systems.  If they are reported to me, they can probably be fixed for
+the next version.
+
+@section Bug Reports
+
+Please send any comments or bug reports to the principal author: Ken
+Raeburn, @t{Raeburn@@Athena.MIT.EDU}.
+
+@section Acknowledgements
+
+I would like to thank: Bill Sommerfeld, for his help with some of this
+documentation, and catching some of the bugs the first time around;
+Honeywell Information Systems, for not killing off the @emph{Multics}
+operating system before I had an opportunity to use it; Honeywell's
+customers, who persuaded them not to do so, for a while; Ted Anderson of
+CMU, for catching some problems before version 1.2 left the nest; Stan
+Zanarotti and several others of MIT's Student Information Processing Board,
+for getting us started with ``discuss,'' for which this package was
+originally written; and everyone I've talked into --- I mean, asked to read
+this document and the ``man'' pages.

+.TH COMPILE_ET 1 "22 Nov 1988" SIPB
+.SH NAME
+compile_et \- error table compiler
+.SH SYNOPSIS
+.B compile_et
+file
+.SH DESCRIPTION
+.B Compile_et
+converts a table listing error-code names and associated messages into
+a C source file suitable for use with the
+.IR com_err (3)
+library.
+
+The source file name must end with a suffix of ``.et''; the file
+consists of a declaration supplying the name (up to four characters
+long) of the error-code table:
+
+.B error_table
+.I name
+
+followed by up to 256 entries of the form:
+
+.B error_code
+.I name,
+"
+.I string
+"
+
+and a final
+
+.B end
+
+to indicate the end of the table.
+
+The name of the table is used to construct the name of a subroutine
+.I initialize_XXXX_error_table
+which must be called in order for the
+.I com_err
+library to recognize the error table.
+
+The various error codes defined are assigned sequentially increasing
+numbers (starting with a large number computed as a hash function of
+the name of the table); thus for compatibility it is suggested that
+new codes be added only to the end of an existing table, and that no
+codes be removed from tables.
+
+The names defined in the table are placed into a C header file with
+preprocessor directives defining them as integer constants of up to
+32 bits in magnitude.
+
+A C source file is also generated which should be compiled and linked
+with the object files which reference these error codes; it contains
+the text of the messages and the initialization subroutine.  Both C
+files have names derived from that of the original source file, with
+the ``.et'' suffix replaced by ``.c'' and ``.h''.
+
+A ``#'' in the source file is treated as a comment character, and all
+remaining text to the end of the source line will be ignored.
+
+.SH BUGS
+
+Since
+.B compile_et
+uses a very simple parser based on
+.IR yacc (1),
+its error recovery leaves much to be desired.
+
+.\" .IR for manual entries
+.\" .PP for paragraph breaks
+
+.SH "SEE ALSO"
+com_err (3).
