parsecfg.py :: parse ios config to python dictionary.

To see how it'll be parsed use CLI in two possible ways:

• python3 parsecfg.py config-ios.sample (get config from specified file)
• python3 parsecfg.py (interactively asks ip, user, password to connect to device and get config)

To use as a library in your code put parsecfg.py to your project folder, then import and use:

from parsecfg import build_dict
dct = build_dict(your_config)

Script parse config to dict of lists (or dict of dicts of lists for "deep" sections of config). If key is starting with '#', than it means it's not a part of config, but just a key containing list of similar commands (about same thing). Resulting dict looks like this:
