There's a new patch below which does the same thing re-using the ttree
code, or something similar. Like ttree, it supports an rcfile (~/.tpagerc),
the -f option to load other configuration files, -h for help, and of course
all the other relevant TT options.
Please eyeball it, check it, confirm it works as expected, and I'll commit
it to CVS. We're still short of the appropriate documentation patch, if
anyone feels so inclined....
And finally, thanks to Slaven for the original patch, and to Myk for the prod.
Cheers
A
