Add option to wrap as a different name

[tesujimath]

I have a number of conda environments containing different versions of a program, which I would like to wrap with unique (i.e. changed) names.

This seems like a simple thing to add, and I would be happy to contribute a pull request, if you agree.

I envisage a new command line option, say --wrap-files-as, which takes a colon separated list of names, which must be the same length as the --files-to-wrap list. (Otherwise, a fatal error.)

Regarding implementation, I think get_files_to_wrap() should in this instance return a list of tuples, which just get passed transparently through to _create_wrappers(). If this is passed a list of tuples, instead of a list of strings, it would create files named as per the --wrap-files-as list. If passed a list of strings as now, it would continue with the current behaviour. (This makes the code changes very localised.)

What do you think?

Hi @tesujimath, thanks for the suggestion.
As long as we don't break the current behaviour, adding this option seems reasonable to me.
I'll gladly accept the contribution :)

I have had a rethink about my use-case which was driving this desire, and it's not sufficiently strong for me to justify spending time working on this. So, I won't be contributing a pull request for this after all.

If it doesn't seem that useful to you, please feel free to close this issue.

Thanks for the follow up @tesujimath. I'll leave it open for some time.
