24 # To use it, just run this script with the top-level sourec directory
25 # as your working directory.
27 # If CDPATH is set, it will sometimes print the name of the directory
28 # to which you have moved. Unsetting CDPATH prevents this, as does
29 # prefixing it with ".".

45 The default behaviour is to check out the Gnulib code via anonymous
46 CVS (or update it if there is a version already checked out). The
47 checkout or update is performed to the gnulib version indicated in
48 the configuration file $configfile.
50 If you wish to work with a different version of gnulib, use the -d option
51 to specify the directory containing the gnulib code.
