- Run (new) filter:

  perl -p -i ~/bin/bracePurgeRef

   >> had some older code that used (\eqnref) and (\cite).  Strip out the braces (leave the formatting to the ref and cite macros used, and change those globally if desired).

- generate the \myTime command used in FrontBackmatter/Titleback.tex, FrontBackmatter/Titlepage.tex

  (changed: make.rules & ~/bin/mkRevInfo)

- spelling: indexes -> indices

   perl -p -i -e 's/indexes/indices/g;'

- diff the latex for gabook since last posted version and prepare a v.12 Changelog record (repost after reworking Stokes theorem content).
