WxFileRenamer is a small GUI utility for renaming files in a directory
with regular expressions. The dialog consists of a console window for
text feedback followed by the three text fields: Dir, Search, and Replace
plus buttons for Simulate, Execute, and Quit.
Instructions:
* Use the command line or drag'n'drop to run WxFileRenamer with the path
to a file whose name is to be changed.
* The directory path will appear in the Dir text field. The filename will
appear in the Search and Replace fields.
* Modify the Search and Replace regular expressions as desired.
* Click "Simulate" button to view effects of current Search and Replace
expressions on directory files without actually renaming files.
* Click "Execute" button to rename files according to Search and Replace
expressions.
* Click "Quit" button or select File\Quit from menu to exit application.
Requires wxPython -- download from http://www.wxpython.org/download.php.

I want an easy, flexible way to rename a group of files without writing small programs or working from the command line. I want to use regular expressions instead of glob or DOS wildcards. I want to set this task up with a minimum of keystrokes and mouse actions. And most important, I want to be able to simulate my renaming strategies before committing the changes to disk.
Plus I prefer wx for a cross-platform work to Tk so I wanted to write this utility in wx. It's a decent example of wx programming that can be used as a skeleton for further utility apps.
In the future I might add an "Undo" button for undoing renames after clicking the "Execute" button.
