* c/src/exec/score/tools/sh - NEW DIRECTORY - contains shgen
Most of it should be self-explanatory. I am a little bit concerned about
host-dependent features (getopt, floating point libraries). This
shouldn't disturb much now, as this tool should be compileable on all
gnu-based hosts and is only applicable for the sh. But in case somebody
complains, we may need to add autoconf checks or even restructurize
parts of rtems (IMO, rtems needs to be restructurized - remember the
"turning rtems upside down" issue).
