[Freeswitch-dev] ESL, Swig and C#

I am about to embark on building a patch that will build a C# version of ESL using Swig What is the preference - hardcoding the rebuild into the VS project, nmake, .cmd or .bat? The biggest issue will be the location of swig - either that goes into the environment vars or I point to a location on my drive. Would it be possible to include it in a download or something like the other libs? Any help in direction is very welcome. Thanks!
