Research direction

Start by reproducing the failure with the requirements.txt example and read PEP 496 and PEP 508 to understand environment markers. Trace how fades processes requirements passed to fades -r; done means the shown marker is handled correctly without causing the command to fail, with tests covering the behavior.

Written by the indexing model from the issue text.

Description

Recently a "fades -r requirements.txt" failed because in the file there was something like:

pysha3==1.0b1; python_version < '3.6'

A quick search showed two PEPs that may be relevant:

https://www.python.org/dev/peps/pep-0496/
https://www.python.org/dev/peps/pep-0508/

Fades should "do the right thing" :)
