+Bootstrap this package from the checked-out sources.
+
+Options:
+ --gnulib-srcdir=DIRNAME Specify the local directory where gnulib
+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ do not want to waste your bandwidth dowloading
+ them again.
+ --copy Copy files instead of creating symbolic links.
+ --force Attempt to bootstrap even if the sources seem
+ not to have been checked out.
+ --skip-po Do not download po files.
+ --cvs-user=USERNAME Set the CVS username to be used when accessing
+ the gnulib repository.
+
+If the file .bootstrap.conf exists in the current working directory, its
+contents are read as shell variables to configure the bootstrap.
+
+Running without arguments will suffice in most cases.
