#!/usr/bin/python

# Builds all projects in the provided solution in a parallel way.

# Usage: "fast_build $Solution $Configuration $Platform"
# Where: $Solution - Path to a .sln file, e.g. Banshee.sln
# Where: $Configuration - e.g. Debug, OptimizedDebug, Release
# Where: $Platform - x86, x64

# Usage example: fast_build Banshee.sln Debug x64

# msbuild must be available in the PATH variable, or the script must be ran from VS or VS Command Prompt
