  Portage split install project (backward compat):

   app-office/openoffice example:
    - define EPACKAGES="core kde gnome templates java"
      => this will install:
         app-office/openoffice-core
         app-office/openoffice-kde
         app-office/openoffice-gnome
         app-office/openoffice-templates
         app-office/openoffice-java
     - src_prepare, src_unpack, src_compile are the same
     - pkg_preinst, pkg_postinst, pkg_prerm, pkg_postrm are the same
     - for every EPACKAGES entry there must be a defined epackage_${EPACKAGE}_src_install, if not: die
     - every EPACKAGES entry can have extra epackage_${EPACKAGE}_pkg_{preinst,postinst,prerm,postrm}
     - every EPACKAGES entry must feature RDEPEND/DEPEND/PDEPEND separate entries, for example:
         => EPACKAGE_${EPACKAGE}_{R,P}DEPEND
     - every EPACKAGE entry automatically depends on app-office/openoffice
