-# SYNOPSIS
-#
-#   AX_PROG_FLEX_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
-#
-# DESCRIPTION
-#
-#   Makes sure that flex version is greater or equal to the version
-#   indicated. If true the shell commands in ACTION-IF-TRUE are executed. If
-#   not the shell commands in commands in ACTION-IF-TRUE are executed. If
-#   not the shell commands in ACTION-IF-FALSE are run. Note if $FLEX is not
-#   set (for example by running AC_CHECK_PROG or AC_PATH_PROG) the macro
-#   will fail.
-#
-#   Example:
-#
-#     AC_PATH_PROG([FLEX],[flex])
-#     AX_PROG_FLEX_VERSION([2.5.39],[ ... ],[ ... ])
-#
-#   This will check to make sure that the flex you have is at least version
-#   2.5.39 or greater.
-#
-#   NOTE: This macro uses the $FLEX variable to perform the check.
