@majorheading Synopsis

@smallexample
AX_PATH_MISSING(VARIABLE, PROG-TO-CHECK-FOR, WARNING-IF-NOT-FOUND, PATH)
@end smallexample

@majorheading Description

Check whether program PROG-TO-CHECK-FOR exists in path. If it is found,
set VARIABLE to the full path of PROG-TO-CHECK-FOR, otherwise warn using
the string WARNING-IF-NOT-FOUND and set VARIABLE to the full path of the
Automake missing script with PROG-TO-CHECK-FOR as the command to run.

A typical use is the following:

@smallexample
  AX_PATH_MISSING([AUTOGEN],[autogen],[autogen seems missing ...])
@end smallexample

This macro is the combination of AC_PATH_PROG and AX_MISSING_PROG. If
you do not want to run AC_PATH_PROG, simply use AX_MISSING_PROG or
AM_MISSING.
