[hlx] release of Hyperlatex 2.7

[<to...@as...>]

Rather than wait for me to figure out the ins and outs of writing
configure and install scripts, I've forged ahead and would like to
announce that

  Hyperlatex version 2.7 is available at hyperlatex.sourceforge.net, 
  to those who would like it.

The thumbnail version of release notes:

This version:

  o Removes dependency on GIF images, replacing them with PNG.  (This
    is relevant both to the documentation and to the bitmaps generated
    for the "image" environment.
  o Includes some new contributed code, notably Ralf Hemmecke's work.

That's all, except that a bug fix submitted in 1999 for version 2.4
was somehow either incompletely applied to that version, or partially
backed out of version 2.5.  (I don't have the records to determine
what went wrong.)  The bug was related to the sequential.hlx package,
and would cause hyperlatex to fail when it was encountered.  The fix
has been re-applied for version 2.7.

Thanks for your attention,
