-- changes to make documentation build with moofglos.fs
   rather than with mini-oof.fs (since the former contains glossary
   entries and the latter does not)

assert.fs blocks.fs debug.fs environ.fs errors.fs extend.fs float.fs
glocals.fs moofglos.fs prim search.fs struct.fs stuff.fs vt100.fs
kernel/args.fs kernel/basics.fs kernel/comp.fs kernel/cond.fs
kernel/files.fs kernel/getdoers.fs kernel/int.fs kernel/io.fs
kernel/nio.fs kernel/paths.fs kernel/require.fs kernel/special.fs
kernel/tools.fs kernel/toolsext.fs kernel/vars.fs

-- many small changes to glossary entries.. I think most are done
   now, so I hope to change far fewer files next time!

doc/gforth.ds

-- many, many small changes and a few large ones. Moved some sections
   around, fixed typos and formatting errors, added new section on
   exception handling, rearranged 'files' section.
