#   Description
#
#       This is a GNU Makefile that uses GNU compilers, linkers and cpp. The
#       platform specific issues are determined by the various OS teets that
#       rely on the uname(1) command and directory locations.
#
#       Set additional flags for the build with variables CFLAGS_USER,
#       DEFS_USER and LDFLAGS_USER.

# Because there is so much trouble with generating man pages with
# pod2man, due to old Perl versions (< 5.10.1) on many systems, I include the
# man pages in the source tar file.
# Old pod2man versions do not have the --utf8 option. Old pod2man, pod2text,
# and pod2html do not support the =encoding command.
# Perl 5.18 pod2man demands an =encoding command for Latin-1 encoded POD files.
#
# Newer perl/pod2man versions produce better output. It is better to include
# man pages in the source package, than that people generate them themselves
# with old perl versions.
