3# This script is a work-alike of `aclocal' contained in the GNU automake
4# package. It is needed because our aclocal.m4 must be generated from the
5# non-gettext .m4 files in /usr/share/aclocal and from the gettext specific
6# .m4 files in the local m4 directory.
7# With   "aclocal --acdir=m4"
8# we get an error: macro `AM_INIT_AUTOMAKE' not found in library
9# With   "aclocal -I m4"
10# we get an error: duplicated macro `AM_GNU_GETTEXT'
11# The solution is to put all the .m4 files into a temporary directory.
