That is a good way to look at it. I imagine in a one way setup, the script invoked would be responsible to place all the necessary executable files, module...

One warning/suggestion I think would be useful is in dealing with optional arguments. A safe style of programming dictates keyword arguments should be used with optional dummy variable (the issue...

The integer overflow error at runtime seems to be triggered by the _debug_ NAG compiler flag https://github.com/fortran-lang/fpm/blob/bb449174631be989fae08532de31e94bac5c5ac3/src/fpm_compiler.f90#L179 which also includes the [option](https://www.nag.com/nagware/np/r70_doc/nagfor.html#OPTIONS): > intovf | (check for integer overflow),

The first error looks mysterious. Is the error `test/cli_test/cli_test.f90: In function ‘main_IP_parse’:` occuring at compile time or when running the test?

A nice summary of the wraparound behavior in practice, and the flags needed to allow it, are given in the [stdlib_hash](https://stdlib.fortran-lang.org/page/specs/stdlib_hash_procedures.html) module specs (thanks to @wclodius2): > In order to...
