.Synopsis
    Build Cmder
.DESCRIPTION
    Use this script to build your own edition of Cmder

    This script builds dependencies from current vendor/sources.json file and unpacks them.

    You will need to make this script executable by setting your Powershell Execution Policy to Remote signed
    Then unblock the script for execution with UnblockFile .\build.ps1
.EXAMPLE
    .\build.ps1

    Executes the default build for Cmder; ConEmu, clink. This is equivalent to the "minimum" style package in the releases
.EXAMPLE
    .\build.ps1 -Compile

    Recompile the launcher executable if you have the requisite build tools for C++ installed.
.EXAMPLE
    .\build.ps1 -Compile -NoVendor

    Skip all downloads and only build launcher.
.EXAMPLE
    .\build -verbose

    Execute the build and see what's going on.
.EXAMPLE
    .\build.ps1 -SourcesPath '~/custom/vendors.json'

    Build cmder with your own packages. See vendor/sources.json for the syntax you need to copy.
