pack.ps1

# This PowerShell script builds the FParsec NuGet packages. 
# Currently, it uses msbuild and needs to be run in the VS2017 Command Prompt, 
# so that it can build PCL assemblies. 
# It also requires the nuget.exe, see $nuget below.
#
# Run this script from the VS2017 Command Prompt, e.g. with 
# powershell -File pack.ps1 -versionSuffix "" > pack.out.txt
