This is a Perl 6 program to create half-sheets (using American sizes, so 8.5x5.5) of ringing performances.

There are hard-coded things related to the Boston (USA) towers, including special logos and text.

You call it as

	gentroff.pl6 -performance=pid -force -groff -image=bcr

The performance id is from BellBoard. (You can also use -p)

By default, it won't do anything for an already existing performance, in case you've customized the .groff output file. To force it to overwrite the existing file, pass -force (or -f).

If you know which logo you want to include, you can pass the name of a file (without the .pdf extension) to the -image (-i) parameter. If you don't want an image, specify "none". Otherwise, it tries to guess based on the association reported by BellBoard.

The program generates a .groff output file, and if you want to run the groff command line as a part of the program, you can pass -groff (or -g). (This is optional in case you want to make changes to the output before creating the .pdf.)

This requires groff version 1.22 (maybe a lower one will work, but I don't know). (It must support the -Tpdf output device.)

(I really want a version of troff that can handle fonts without having to jump through hoops.)
