How to have two parallel emacs environments?

[Guido Van Hoecke <guivho@gmail.com>]

Hi,

I would like to reorganise and actualise my emacs current setup files.

To facilitate this time consuming and laborious process I would really
like to experiment in a temporary second emacs environment which would
gradually be extended to eventually provide at least the support
currently provided by my official setup.

I was hoping that I could start an alternate emacs using the -u option so
that I could get a separate instance using the growing new setup file.
But obviously that does not work as it expects a user name, not an init
file path.

Is there any way to launch an emacs with a specific init file?

Or is there a different approach to this problem?

Thanks in advance for your suggestions and ideas,


Guido
