o Typo and style fixes

... sometime in the future

* Add an `install_macros' (or the like) to makefile.loc to automate macro installation
  for the parser generated by this package (the parsers and lexers are not separated
  into different directories, the new targets are `install' and `uninstall')
* Fix the double column output macros to correctly process the \mark commands (every time
  an output routine runs it resets the \topmark; this needs to be corrected) 
* Change generic macro names (such as \table) to something more specific (\table will stay
  but most macro names are unique enough)
* Add a macro to index arbitrary strings in an arbitrary domain (store the string in a
  global array and pass the pointer to the indexing macros)
* Reimplement the action for the bison parser using lists
* Add \bgrulealign and \egrulealign macros to align rules across sections (a simple way to 
  implement this is given as an example in the included package, a more flexible method would 
  have to wait)
* Rewrite yytexlex.sty for better \TeX\ pretty printing macros (* the new macros are still
  not ideal but are very unlikely to change in the near future)
  * Change the name of the namespace (currently `index') used by the \TeXx macros to avoid
    confusion with the special `[index]' namespace used by the parser for inserted symbols
    (like an empty right hand side and implicit terms) (`index' has been changed to `index:tex') 
  o Develop a 'loose' parsing scheme for \TeX\ macros by requiring some macros to
    follow stricter rules
* Rewrite limbo.sty to provide a more logical structure (* several changes have been implemented)
* Add indexing features to \TeXx macros (* there is a mechanism to do this)
o Optimize \yyinput to minimize expansion in the most common cases
o Change CWEB macros so that \pdfoutput=0 does not cause conflicts (this is a bug in cwebmac.tex)
* Change the support for named references so that the driver generates references while outputting
  the 'action switch' (using code like stack_depth = $$ - $[name];* done using `lazy' postprocessing)

... very remote future

o Make glr parser generation possible (* probably not feasible with
  the current state of bison design, likely to require a fork or even
  a completely different tool)
o Make the `core' parsing and scanning macros prefix-expandable

... very very remote future

o Make automatic translation of \Cee\ into \TeX\ possible so that
  bison routines can be simply translated on the fly.
