GNU `m4'
|
||
|
|
********
|
||
|
|
|
||
|
|
GNU `m4' is an implementation of the traditional UNIX macro
|
||
|
|
processor. It is mostly SVR4 compatible, although it has some
|
||
|
|
extensions (for example, handling more than 9 positional parameters to
|
||
|
|
macros). `m4' also has builtin functions for including files, running
|
||
|
|
shell commands, doing arithmetic, etc. Autoconf needs GNU `m4' for
|
||
|
|
generating `configure' scripts, but not for running them.
|
||
|
|
|
||
|
|
GNU `m4' was originally written by Rene Seindal, with subsequent
|
||
|
|
changes by Franc,ois Pinard and other volunteers on the Internet. All
|
||
|
|
names and email addresses can be found in the file `THANKS' from the
|
||
|
|
GNU `m4' distribution.
|
||
|
|
|
||
|
|
This is release 1.3. It is now to be considered stable, future
|
||
|
|
releases are only meant to fix bugs, increase speed, or improve
|
||
|
|
documentation. However...
|
||
|
|
|
||
|
|
An experimental feature, which would improve `m4' usefulness, allows
|
||
|
|
for changing the syntax for what is a "word" in `m4'. You should use:
|
||
|
|
./configure --enable-changeword
|
||
|
|
|
||
|
|
if you want this feature compiled in. The current implementation slows
|
||
|
|
down `m4' considerably and is hardly acceptable. So, it might go away,
|
||
|
|
do not count on it yet.
