+# 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>.
