Re: allowing users to add source files without rerunning the autotools?

[Bill Sacks]

Hi Jeff & Miles,

Thank you both for your helpful replies. 

The dependency issue that Jeff raised is not a problem for us, since we have a 
script to determine Fortran 90 dependencies.

I'm not sure that it will work to have a separate library of the user-added 
code, since we don't know ahead of time what dependencies there will be between 
existing code and the user-added code.

Your other suggestions are helpful. We'll give this some more thought.

Thanks again,
Bill
