[MonoDevelop] project files what are they for?

[Ronaldo Nascimento]

What are these Monodevelop project files for? And should they be
included in version control?


in the solution i have:

TravTasks/TravTasks.sln
TravTasks/TravTasks.userprefs
TravTasks/TravTasks.usertasks

then in the project folder i have:
TravTasks/TravTasks/TravTasks.csproj
TravTasks/TravTasks/TravTasks.pidb

can seem to find any docs on this either

thanks
