Configuration Mechanism
-----------------------
-Starting from 0.99.9 (actually mid 0.99.8.GIT), `.git/config` file
-is used to hold per-repository configuration options. It is a
-simple text file modeled after `.ini` format familiar to some
-people. Here is an example:

------------

; user identity
[user]
name = "Junio C Hamano"
- email = "junkio@twinsun.com"
+ email = "gitster@pobox.com"

Various commands read from the configuration file and adjust
their operation accordingly. See linkgit:git-config[1] for a
