Subcommands:

- list: List the active configuration (or from the file specified)

- edit: Edit the configuration file in an editor

Configuration keys should be dot separated command and option name,

with the special prefix "global" affecting any command. For example,

"pip config set global.index-url https://example.org/" would configure

the index url for all commands, but "pip config set download.timeout 10"

would configure a 10 second timeout only for "pip download" commands.

environment configuration file is used if one is active and the file

default.
