There are others and you should consult the gnu M4 manual for further information. M4 includes a set of pre-defined macros that make it substantially more useful. Some common M4 idioms have developed for this purpose and are covered in Ajtobook You will notice in much of the documentation for existing Autoconf macros that arguments may be left blank to accept the default value.

The task of then locating the troublesome shell gnh in the input files can be potentially quite difficult. It is worth highlighting again the liberal use of quoting. Thus, m4 will appear to consume macro invocations like these from the input. Libtool-related questionsPrevious: This process is known as expansion — even if the new text may be shorter!

Magic happens under the hood, where experts have tinkered until the GNU Autotools engine can run on everything from jet fuel to whale oil. This book stands a level above the software packages, giving the expertise of its authors in using this whole system to its fullest.
