Re: [Groff] trap problem

[Clarke Echols]

I'm not familiar with the MS macro package, but the man package
I worked with 15-20 years ago does a top-of-page routine.  You
can take the page number, check for even/odd, and alter the page
offset accordingly.  Just make sure you do it before anything
gets sent to output storage for post-processing (i.e. before
any vertical positioning occurs).  This probably means putting
it at the start of the top-of-page macro, or redefining the macro
in your file(s) if you don't want to edit the ms macros themselves.
