Copying and distribution of this file, with or without modification,

This file contains information that supplements the generic
installation instructions in file `INSTALL.autotools'.
If you want to start compiling the `groff' system with an existing
script `configure' you won't need the information ion this file.
But if you want to use the `GNU autotools' (`aclocal', `autoreconf')
for creating the following and some more files:
aclocal.m4
configure
Makefile
To change the file `aclocal.m4', run the shell command
$ aclocal -I m4
To recreate the files `configure' and `Makefile', use the shell command
$ autoreconf -I m4
The option `-I m4' is necessary. It refers to the subdirectory `m4'
that has files with m4 macro definitions that are needed by the
`autotools'.
If you use an old `autoreconf' version < 2.69, there might be an
error warning like:
/usr/share/aclocal/gtkglextmm-1.2.m4:225: warning: underquoted \
definition of AC_GTKGLEXTMM_SUPPORTS_MULTIHEAD
/usr/share/aclocal/gtkglextmm-1.2.m4:225: run info \
'(automake)Extending aclocal'
/usr/share/aclocal/gtkglextmm-1.2.m4:225: or see \
http://www.gnu.org/software/automake/manual/automake.html#Extending-aclocal
Just ignore this. It doesn't occur in the actual versions of `autoreconf'.
You may even use the shell command
$ autoconf
instead of `autoreconf', but that will ignore some features. So
`autoreconf' is better.
`automake' is not used. `autoreconf' does part of this. If you know
about creating `Makefile.am' files we are glad to have you for the
inclusion of `automake'. Take contact with the `groff Mailinglist'.
After the use of the `GNU autotools', the usual compilation should
work. If the run of `configure' produces error reports you have
produced errors in the `autotools' modification.
