Implemented actual renaming token substitution logic. ...

Implemented /$ENVVAR/ renaming token support.

Added code to __ResolveRenameTokens() to detect renaming tokens in a string, determine their contents, and flag missing delimiters.

Cosmetic cleanup in preparation for rename token processing. ...

Changed regex processing to use match.span() rather than match.start() and match.end().

Consolidated all test mode reporting down into __RenameIt() so that -t will also show any required backup operations.

Fixed a bug that occured when multiple renames iterated over the same filename.

First cut at regex-based matching. ...

-E option removed.  All ErrorMsg calls terminate program immediately now.

Added more bounds checking for individual replacement instance values.

Changed renaming logic to only rename the instances specified on the command line via -i.

Changed -i parsing logic to look for python-style indexes or slice ranges.

Began implementing new logic for selecting replacement "instances". ...

Initial revision

Changed Rename() to ProcessRenameRequests(). ...

Got rid of the whole name/ext/all target paradigm, thereby eliminating -a, -b, -e, and -L options.

Simplified test mode reporting to only show top level renames and not any consequence backups or skips. ...

Implemented live file renaming.

Moved checks for existing targets from Rename() to RenameIt(). ...

Made check for existing target recursive so existing backups would get backed up.
Implemented min/max new filename length enforcement.

Began restructuring Rename() and added a new supporting RenameIt() method.

Added -P option to allow user to specify their own escape character.

More cosmetic cleanup.

Changed -v so it dumps and *continues* - this allows its output to be included in a rename output log.

Minor cosmetic cleanup.

Added logic for dumping test output. ...

Added InfoMsg().
Began implementing logic for forced renaming of existing targets.
Added -S option to override forced renaming suffix.

Modified ErrorMsg to accept and optional EXIT argument. This gets rid of most of the sys.exit(1)s that littered the code. ...
