[GRASS-dev] Using a dynamic text in module header for parser

[Michel Wortmann]

Sorry, I thought I had tested it with some changes I made afterwards, 
this end part works better:

     startcmd = 'python '+s.name
     # set env variable
     tmpdir = os.path.dirname(s.name)
     os.environ['GRASS_ADDON_PATH']=tmpdir
     # set permissions
     os.chmod(s.name, os.stat(s.name).st_mode | stat.S_IEXEC)
     # start module
     os.system(startcmd)
     os.remove(s.name)
