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