FreeArc+InnoSetup support

Recently, FreeArc becomes very popular for making installers of multi-gigabyte programs. It's the only archiver that support dictionaries up to 2gb, that makes its archives smaller than ones made by 7-zip or any other archiver. We provide this package in order to help authors of those installers.

It includes unarc.dll for decompression of FreeArc archives inside InnoSetup installers, and two example installer scripts using this dll - basic and extended. You will find detailed instructions in the sample scripts. Ask questions about script usage in the forum.

If you are using FreeArc archives in your installers - please add there link to FreeArc site in order to promote FreeArc.
