If true the shell 13# commands in ACTION-IF-TRUE are executed. If not the shell commands in 14# ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by 15# running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail. 16# 17# Example: 18# 19# AC_PATH_PROG([PYTHON],[python]) 20# AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ]) 21# 22# This will check to make sure that the python you have supports at least 23# version 2.4.4. 24# 25# NOTE: This macro uses the $PYTHON variable to perform the check. 26# AX_WITH_PYTHON can be used to set that variable prior to running this 27# macro. The $PYTHON_VERSION variable will be valorized with the detected 28# version. 29# 30# LICENSE 31# 32# Copyright (c) 2009 Francesco Salvestrini <salvestrini@users.sourceforge.net> 33# 34# Copying and distribution of this file, with or without modification, are 35# permitted in any medium without royalty provided the copyright notice 36# and this notice are preserved.
