contrib/egcs_update

   1 #! /bin/sh
   2 #
   3 # Update a local CVS tree from the egcs repository, with an emphasis
   4 # on treating generated files correctly, so that autoconf, bison et
   5 # al are not required for the ``end'' user.
   6 #
   7 # By default all command-line options are passed to `cvs update` in
   8 # addition to $UPDATE_OPTIONS (defined below). If the first parameter
   9 # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself
  10 # are omitted.
  11 #
  12 # Examples:
  13 #
  14 # contrib/egcs_update -r egcs_latest_snapshot
  15 # contrib/egcs_update -A
  16 # contrib/egcs_update --nostdflags -P -r egcs_1_1_branch gcc/testsuite
