On the rare occasions when I make a program that's generic enough to be used more than once, I'll post it here.

astring

Extracts or reinserts strings from .txt files. Useful for checking spelling and grammar.

RBDiff

Performs a byte-by-byte comparison of two files with diff-like output.

sdfgrep

Prints out all occurances of a certain SDF in .txt files.

randtext

Creates AvernumScript code for a random dialog box. Or something like that.

depchart

Creates a GraphViz .dot file for all import dependencies in a definition file (don't worry if you didn't catch that).
