Hello, 

I'm using txt2man, and it's producing some not-quite-right output.  I want
to tweak it, but I can't seem to find the nroff (?) macros that man pages
use.  

I've read the mdoc stuff, but of course that describes mdoc input, not
mdoc output.  

For instance, I'm looking at txt2man output like:

	.SH NOTES

	To date, freebcp has been tested ...
	.TP
	.B
	When connecting to ...

and I don't know where to read about .B and friends.  

TIA
