If you are looking for an easy way to make an cab installation file then look no further. Cab-O-Matic is the first online cab maker for windows mobile. Its in beta and is online now.

Use of Cab-O-Matic is simple:

• Zip up the files you want cabbed (including optional .reg file)
• Upload the .zip
• Click a few boxes
• Download your .cab!

Limitation : Currently, you can only use DWORD and STRING as datatypes for registry settings. Support for binary and multi-string datatypes will be along shortly! Finally, you cannot currently define program menu shortcuts.
