dnl SYNOPSIS
dnl
dnl   AX_WITH_PROG([VARIABLE],[program],[VALUE-IF-NOT-FOUND],[PATH])
dnl
dnl DESCRIPTION
dnl
dnl   Locates an installed program binary, placing the result in the precious
dnl   variable VARIABLE. Accepts a present VARIABLE, then --with-program, and
dnl   failing that searches for program in the given path (which defaults to
dnl   the system path). If program is found, VARIABLE is set to the full path
dnl   of the binary; if it is not found VARIABLE is set to VALUE-IF-NOT-FOUND
dnl   if provided, unchanged otherwise.
dnl
dnl   A typical example could be the following one:
dnl
dnl         AX_WITH_PROG(PERL,perl)
dnl
dnl   NOTE: This macro is based upon the original AX_WITH_PYTHON macro from
dnl   Dustin J. Mitchell <dustin@cs.uchicago.edu>.
