Adjust the module/library terminology

[bythos14]

Deprecates the use of 'modules' in the export configuration.

can you explain why do you want to change the name?
(and it need to add into commit message)

[SonicMastr]

The "module" is the actual PRX itself. A module can have multiple libraries, not the other way around. It's to be consistent with pretty much everything else to avoid confusion

[bythos14]

As SonicMastr said, consistency. The import configuration yml has the correct use of the 'modules' and 'libraries', this just makes the export configs consistent with that.

It's relevant to issue #48.

i got it. so modules of exports.yml have to be just module. but this exports.yml is already a description of the module.
so you use libraries instead of module. right?
(and i checked the imports.yml case, and yes, it was already changed 6yr ago.)

1. please update commit description about this.
2. after this pr, we might have to update the specfication document; but only @yifanlu has a source.. :'(

[SonicMastr]

That is correct

@d3m3vilurr I've updated the commit description
