Usage: $0 [-c] [-s] [-t] [-T target] [chapters]

-s: Replaces external xrefs in each chapter, so each chapter works standalone.

-t: Does what -s does, but also prevents most glossary processing so the glossary building goes much faster.

-c: Coverage mode.  Instead of using the normal chapter data, runs a special small file that is designed to do everything we ever do, but runs very quickly.  In this case, the 'chapters' argument is one or more coverage types to run.  Possible coverage types:

$(ls $(pwd)/coverage/*.xml | xargs -n 1 basename | sed 's/^coverage_//' | sed 's/\.xml$//')

-T target: Specifies the make target.  Most of them are obvious.  The _web targets copy stuff into your ~/public_html/ web space.  Complete list:

$(grep '^[a-z][a-z_]*:' scripts/Makefile | sed 's/:.*//' | sed 's/^/    /')

[chapters]: defaults to all chapters; if you specify less than all chapters, you must use -s or -t
