+git-config-set(1)
+===============
+
+NAME
+----
+git-config-set - Set options in .git/config.
+
+
+SYNOPSIS
+--------
+'git-config-set' ( name [value [value_regex]] | --unset name [value_regex] )
+
+DESCRIPTION
+-----------
+You can set/replace/unset options with this command. The name is actually
+the section and the key separated by a dot, and the value will be escaped.
+
+If you want to set/unset an option which can occor on multiple lines, you
+should provide a POSIX regex for the value.
+
+This command will fail if
+
+. .git/config is invalid,
+. .git/config can not be written to,
+. no section was provided,
+. the section or key is invalid,
+. you try to unset an option which does not exist, or
+. you try to unset/set an option for which multiple lines match.
+
+
+OPTIONS
+-------
+
+--unset::
+       Remove the given option from .git/config
+
+
+EXAMPLE
+-------
+
+Given a .git/config like this:
+
+       #
+       # This is the config file, and
+       # a '#' or ';' character indicates
+       # a comment
+       #
+
+       ; core variables
+       [core]
+               ; Don't trust file modes
+               filemode = false
+
+       ; Our diff algorithm
+       [diff]
+               external = "/usr/local/bin/gnu-diff -u"
+               renames = true
+
+       ; Proxy settings
+       [proxy]
+               command="ssh" for "ssh://kernel.org/"
+               command="proxy-command" for kernel.org
+               command="myprotocol-command" for "my://"
+
+you can set the filemode to true with
+
+------------
+% git config-set core.filemode true
+------------
+
+The hypothetic proxy command entries actually have a postfix to discern
+to what URL they apply. Here is how to change the entry for kernel.org
+to "ssh".
+
+------------
+% git config-set proxy.command '"ssh" for kernel.org' 'for kernel.org$'
+------------
+
+This makes sure that only the key/value pair for kernel.org is replaced.
+
+To delete the entry for renames, do
+
+------------
+% git config-set --unset diff.renames
+------------
+
+or just
+
+------------
+% git config-set diff.renames
+------------
+
+If you want to delete an entry for a multivar (like proxy.command above),
+you have to provide a regex matching the value of exactly one line.
