ppl [address book] Configuration Guide
[address book] path = ~/contacts
By default, ppl determines the location of the address book based on the user’s working directory. This value overrides that behaviour and sets a particular directory as the location of the address book regardless of the working directory.
This is intended for the typical use-case where a user of ppl only has one address book. The purpose is to increase the convenience of using ppl with that single address book by removing the requirement that the user first navigate to its directory before reading from or writing to it.
