+\`$program' generates RTEMS custom/\*.cfgs and config-files for gcc multilib

+Usage: $program [options]
+
+Options:
+ --target=STRING target
+ --custom generate make/custom/*.cfg files
+ --config generate config scripts
+ --rtems=DIR use \`DIR\' as location of RTEMS source tree
+ -v, --verbose verbose
+ -h, --help Print this usage
+ --version Print version and exit
+
+Examples:
+$program --config --target=sh-rtems --rtems=/usr/src/rtems-4.5.0
+ Generates config scripts for all possible bare BSPs from all
+ valid multilib variants sh-rtems-gcc supports
+
+$program --custom --target=sh-rtems --rtems=/usr/src/rtems-4.5.0
+ Generates /usr/src/rtems-4.5.0/make/custom/*.cfg files
