Build Cmder
.DESCRIPTION
Use this script to build your own edition of Cmder
2014-02-25 00:33:14 +08:00
This script builds dependencies from current vendor/sources.json file and unpacks them.
2014-02-25 00:33:14 +08:00
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
2014-02-25 00:33:14 +08:00
Executes the default build for cmder, this is equivalent to the "minimum" style package in the releases
.EXAMPLE
.\build -verbose
2014-02-25 00:33:14 +08:00
Execute the build and see what's going on.
.EXAMPLE
.\build.ps1 -SourcesPath '~/custom/vendors.json'
2014-02-25 00:33:14 +08:00
