# SYNOPSIS
#
#   AX_PROG_HAXE_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
#
# DESCRIPTION
#
#   Makes sure that haxe supports the version indicated. If true the shell
#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
#   ACTION-IF-FALSE are run. The $HAXE_VERSION variable will be filled with
#   the detected version.
#
#   This macro uses the $HAXE variable to perform the check. If $HAXE is not
#   set prior to calling this macro, the macro will fail.
#
#   Example:
#
#     AC_PATH_PROG([HAXE],[haxe])
#     AC_PROG_HAXE_VERSION([3.1.3],[ ... ],[ ... ])
#
#   Searches for Haxe, then checks if at least version 3.1.3 is present.
