Things that need to be done:
    - regedit:
	- figure out what the bits in the flags field of the various headers
	  mean.
	- sort out warnings generated by win98 registries.
	- do byte swaping as data is read/written (ie, support big endian
	  machines).
	- redo the import file parsing.
	- add more error checking when using the key table (range checking
	  when using rgdb and id; check that key entries don't overlap, etc.).
	- only write out those sections that were changed (when possible).
	- add an option to print out a portion of the registry (ie, everything
	  under a specified key).
	- make regedit more portable (eg, use autoconf, add lots of ifdefs,
	  etc.)
    - IniFile.pm:
	- change to preserve comments in .ini files
	  (update all ini programs if needed).
	- write perldocs for these routines
    - regfilterLib.pm:
	- re-write in oo style (ala IniFile.pm)
	- write perldocs for these routines
    - lots of work on gen-app-changes.pl
	- uses diff -r, which does case sensitive file name matching
    - lots of work on apply-app-changes.pl (re-write?)
	- decide automatically if `new' .dll should replace existing
	  (go with newest version)
    - redo fix-w9x-link.pl (anyone know the format of a .lnk file?)
