Powershell script that will pack and push .nupkg

nuget.ps1

# Nuget packaging thing
#
# Use this guy to pack and push .nupkg from your .csproj
# 
# Note: nuget.exe pack will assume a .nuspec file already exist
# if not then create one yourself: nuget.exe spec.
# This is not done automatically, as you probably wan't to 
# customize this your self, before running this.
# 
# This will check if the assembly version on given project 
# has changed, and if so it will re-pack the project and push 
# it to given gallery 
#
# To use it, make sure nuget.exe is in your csproj root and
# add this post build event to your csproj:
#
# powershell -ExecutionPolicy Unrestricted $(ProjectDir)nuget.ps1 -ProjectDir $(ProjectDir) -TargetDir $(TargetDir) -ApiKey YOUR_SECRET_API_KEY -Server http://YOUR_NUGET_GALLERY.com

# enjoy!
