# OLD14 = 1.4
# OLD15 = 1.5
# NEW = 1.6 (.3)

# NOTE:  For all of those brave souls out there that wants to fix
#        or update this, note that all three versions install
#        .m4 files to /usr/share/aclocal-${ver}/ and .am files
#        to /usr/share/automake-${ver}/.  We then add the default
#        /usr/share/aclocal/ to aclocal's search path by adding
#        "push (@dirlist, \"/usr/share/aclocal\");" after @dirlist
#        is defined the first time (done in fix_bins() function).
#
#        The theory thus is, all version specific data goes into
#        version specific directories, but programs like ogg/whatever
#        can still install thier .m4 macros into /usr/share/aclocal/.

# Currently this is 1.6, but it could change to 1.6.x as it
# does with 1.5d ... to determine this, install latest version
# of 1.6, and look at the generated files in the bin dir ..
# it should be something like (for 1.6.1):
#
# nosferatu automake-1.6.1 # ls /myinstallroot/bin/
# aclocal  aclocal-1.6  automake  automake-1.6
# nosferatu automake-1.6.1 #
#
# You should then set NEW_PV to 1.6, as this is the suffix
