#  This script is a simple script to build and install rtems toolset
#  for the target you specify on the command line.  It should be of
#  the form <CPU>-rtems<VERSION>.  For example, sparc-rtems4.11
#
#  This can be used to build versions from CVS/SVN or released versions.
#  Please be sure to apply appropriate patches from
#  rtems/contrib/crossrpms/patches.
#
#  Currently only testing of non-RTEMS targets is supported.
