Message Base Spy is a convenient tool intended for those who want to have a look into message base internals for research, troubleshooting and development purposes.

Message Base Spy supports Squish, JAM and Hudson (aka QBBS) message bases. If you think there is some other message base format worth supporting, please let me know.

Message Base Spy sports a friendly user interface much like those normally found in modern GUI environments. So click, double click, right click, scroll, tab/backtab, shift select, cut and paste, etc. just like you would do in you know where.

Message Base Spy comes with C-language headers for all the message bases it supports and contains relevant pieces of the original authour's documentation explaining particular message base structure.
