There's over 18mb of source there, so it will be easiest for you to checkout just the projects you need. Simply append the tool's name to the checkout source when checking out. IE:
- ICE:
http://code.google.com/p/allegice/ - AGM, AME, AMT, BetaRegistryHelper, CRC, CoreDump, CoreTool, ICE (old), IGCVal, MDLView, ObjRef2String, TAG, TEK, Update:
http://svn.alleg.net/svn/AllegThirdParty/ - Installer:
http://svn.alleg.net/svn/Installer_Client
http://svn.alleg.net/svn/Installer_Server
If you find bugs in any of these programs and have fixed the problem in your checkout, create a patch and PM me so it can be fixed.
Keep on coding,
