Unless they did what Schobi did (twice): type ..\bjam.exe and then
paste the entire command line.

But if a change like that will make a difference, send me your SF user
name and I'll give you CVS access, so you can fix it.

We've always had a binary download for windows available. What more
do you need?

The dash is there for dumb reasons: we call the toolset files


and for the purposes of building a Boost distro on CD we can't have
filenames with multiple '.' characters in them, so we changed '.' to
'_' in the names of things like vc-7.1-tools.jam. But we should have
changed BBv1 to allow users to type a '.' on the command-line and
translate it internally when we made that change; it would be pretty
easy. As for naming consistency, yes, it would probably be better.

BBv2 fixes all of these problems, and we've been reluctant to make
trivial improvements in BBv1 because it's been so long anticipated
that it would be retired. Now it looks like it won't be retired until
just after 1.33, so it's a toss-up whether we should do anything about
it. I'm willing to go either way.
