Support deploying to CRM by providing an API that would support using from a command line or from a .Net app.
Should be able to call an API to publish a crm asset or plugin/workflow assembly to the CRM organization taking into account all the XrmToolkit configuration information.
The initial version of this has been released in v5. It supports merging (ILMerge) of plugin assemblies and publishing them to CRM. A future release will include the ability to deploy other assets, ie web resources etc.

It would be great if API support is extended to web resources upload+publish. This would help in hooking api up as part of CI (npm build) process. A support for separate mapping file would make it configurable like VS extension "Microsoft Dynamics CRM Web Resources Updater".
