I tried dejagnu 1.6.3-rc2.  I ran "runtest" on a subset of the gdb test
suite, and this worked well.  Thank you.

I tried the new "dejagnu" command but noticed two things.

First in --help:

Usage: dejagnu <command> [--help|options...]
Usage: dejagnu --help
Usage: dejagnu --version
        --help			Print help text
        --version		Print DejaGnu version

The GNU norm is to use upper-case for "metasyntactic variables", so
normally it would say "dejagnu COMMAND [...]"

Second, either --help or running it without options should probably show
the available commands.

Third, the use of tabs in the output makes it a bit weird to quote.

thanks,
Tom

Fixed in commit ea9642561c3f410dfb9f1362bc61fdf4e499b7f4 on the 
dejagnu-1.6.3 branch.

The "weird" indentation (unaffected by a small bit of left-edge text) is 
intentional in the script files, since the help messages are embedded in 
comments there.  I will consider possibly expanding tabs on output in a 
future version but this is not really a bug right now.
