Nice, relaxing Perl munging. :) Have another change to put into this 

changeset - afaik, I can edit changesets with bk. So, rather than wait, I will
commit this now, finish up the other code, try to alter the changeset and then
push all the changes up.


Docs/Support/docbook-fixup.pl:
  Rewrote to use a more native Perl style.
  Increase strictness of error checking.
  Simplified and optimized regular expressions.
  Fixed several problems with conversion. Still have some minor issues to sort out.
  Rewrote to accept input from stdin or from filename arg(s) on the command line.
  Improved speed ~6x.
Docs/Support/docbook-split:
  Rewrote to use a more native Perl style.
