# The basic theory based on comments from Daniel Robbins <[e-mail]>.
#
# We split the perl ebuild into libperl and perl.  The layout is as follows:
#
# libperl:
#
#  This is a slotted (SLOT=[0-9]*) ebuild, meaning we should be able to have a
#  few versions that are not binary compadible installed.
#
#  How we get libperl.so multi-versioned, is by adding to the link command:
#
#    -Wl,-soname -Wl,libperl.so.`echo $(LIBPERL) | cut -d. -f3`
#
#  This gives us:
#
#    $(LIBPERL): $& perl$(OBJ_EXT) $(obj) $(LIBPERLEXPORT)
#        $(LD) -o $@ $(SHRPLDFLAGS) perl$(OBJ_EXT) $(obj) \
#              -Wl,-soname -Wl,libperl.so.`echo $(LIBPERL) | cut -d. -f3`
#
#  We then configure perl with LIBPERL set to:
#
#    LIBPERL="libperl.so.${SLOT}.`echo ${PV} | cut -d. -f1,2`"
#
#  Or with the variables defined in this ebuild:
#
#    LIBPERL="libperl.so.${PERLSLOT}.${SHORT_PV}"
#
#  The result is that our 'soname' is 'libperl.so.${PERLSLOT}' (at the time of
#  writing this for perl-5.8.0, 'libperl.so.1'), causing all apps that is linked
#  to libperl to link to 'libperl.so.${PERLSLOT}'.
#
#  If a new perl version, perl-z.y.z comes out that have a libperl not binary
#  compatible with the previous version, we just keep the previous libperl
#  installed, and all apps linked to it will still be able to use:
#
#    libperl.so.${PERLSLOT}'
#
#  while the new ones will link to:
#
#    libperl.so.$((PERLSLOT+1))'
#
# perl:
#
#  Not much to this one.  It compiles with a static libperl.a, and are unslotted
#  (meaning SLOT=0).  We thus always have the latest *stable* perl version
#  installed, with corrisponding version of libperl.  The perl ebuild will of
#  course DEPEND on libperl.
