Writing `configure.ac'
======================
To produce a `configure' script for a software package, create a
file called `configure.ac' that contains invocations of the Autoconf
macros that test the system features your package needs or can use.
Autoconf macros already exist to check for many features; see
Existing Tests, for their descriptions. For most other features, you
can use Autoconf template macros to produce custom checks; see
Writing Tests, for information about them. For especially tricky or
specialized features, `configure.ac' might need to contain some
hand-crafted shell commands; see Portable Shell. The
`autoscan' program can give you a good start in writing `configure.ac'
( autoscan Invocation, for more information).
Previous versions of Autoconf promoted the name `configure.in',
which is somewhat ambiguous (the tool needed to process this file is not
described by its extension), and introduces a slight confusion with
`config.h.in' and so on (for which `.in' means "to be processed by
`configure'"). Using `configure.ac' is now preferred.
