My own package build system :)

This is the first attempt and it's not finished

+#	  and it is also used pr. default as the toplevel name inside the sourcetar ($tarname)
+# version= source version ie. 0.14.2b
+# pkgver= the package revision, an increasing number is recommended but a date could be used instead
+# source[0..x] = source filenames - source[0] *must* be defined and contain a legal filename
+#		pr. default we will look for source[0] relative to $srcfiles
+#		A filename that begin with / will be treated as absolute paths
+#		Note! only source[0] will be automatically unpacked

+#		pr. default we expect these to be listed relative to $srcdir
