# Run this to generate all the initial makefiles, etc.
# This was lifted from the Gimp, and adapted slightly by
# Raph Levien.
# Since then, it has been rewritten quite a lot by misc. people.

# Call this file with AUTOCONF_SUFFIX and AUTOMAKE_SUFFIX set
# if you want us to call a specific version of autoconf or automake. 
# E.g. if you want us to call automake-1.6 instead of automake (which
# seems to be quite advisable if your automake is not already version 
# 1.6) then call this file with AUTOMAKE_SUFFIX set to "-1.6".

# Cases which are known to work:
# 2002-07-14: Debian GNU/Linux unstable with:
#   autoconf 2.53
#   automake 1.4-p5 and 1.6 (both)
#   gettext  0.10.40
#   libtool  1.4.2a
# 2002-07-14: Redhat Linux 7.3 with:
#   autoconf 2.53
#   automake 1.5 (not 1.4-p5)
#   gettext  0.11.1
#   libtool  1.4.2
