Re: GNU coding standards for the --version option

Thanks for the report, which brings to light a worse problem:  The version
timestamp is not regenerated automatically when the distribution is rolled.
Libtool-1.5 should report:

$ libtool --version | head -1
ltmain.sh (GNU libtool) 1.5

The other gubbins is to help us distinguish cvs revisions in bug reports, and
should only be displayed in self built installations.

Anyhow, I think I fixed this in CVS now, as well as moving the information
around to satisfy the standards you cite.

$ ./libtool --version | head -1
ltmain.sh (GNU libtool 1.1350 2003/11/26 15:36:07) 1.5a

Cheers,
        Gary.
