|  |  C.1 aclocal 
The aclocalprogram creates the file `aclocal.m4' by
combining stock installed macros, user defined macros and the contents
of `acinclude.m4' to define all of the macros required by
`configure.in' in a single file.aclocalwas created as
a fix for some missing functionality in Autoconf, and as such we
consider it a wart.  In due courseaclocalitself will
disappear, and Autoconf will perform the same function unaided.
