context exist they all must match. By default no context is
ever ignored.
+--whitespace=<nowarn|warn|error|error-all|strip>::
+ This flag is passed to the `git-apply` program
+ (see gitlink:git-apply[1]) that applies the patch.

Make a list of the commits which are about to be rebased. Let the
user edit that list before rebasing. This mode can also be used to

+'git-remote' add [-t <branch>] [-m <branch>] [-f] [--mirror] <name> <url>
+'git-remote' rm <name>
'git-remote' show <name>
'git-remote' prune <name>
'git-remote' update [group]
With `-m <master>` option, `$GIT_DIR/remotes/<name>/HEAD` is set
up to point at remote's `<master>` branch instead of whatever
branch the `HEAD` at the remote repository actually points at.
++
+In mirror mode, enabled with `--mirror`, the refs will not be stored
+in the 'refs/remotes/' namespace, but in 'refs/heads/'. This option
+only makes sense in bare repositories.
+
+'rm'::
+
+Remove the remote named <name>. All remote tracking branches and
+configuration settings for the remote are removed.
'show'::
Make git-send-email less verbose. One line per email should be
all that is output.
+--identity::
+ A configuration identity. When given, causes values in the
+ 'sendemail.<identity>' subsection to take precedence over
+ values in the 'sendemail' section. The default identity is
+ the value of 'sendemail.identity'.
+
--smtp-server::
If set, specifies the outgoing SMTP server to use (e.g.
`smtp.example.com` or a raw IP address). Alternatively it can
`/usr/lib/sendmail` if such program is available, or
`localhost` otherwise.
+--smtp-server-port::
+ Specifies a port different from the default port (SMTP
+ servers typically listen to smtp port 25 and ssmtp port
+ 465).
+
+--smtp-user, --smtp-pass::
+ Username and password for SMTP-AUTH. Defaults are the values of
+ the configuration values 'sendemail.smtpuser' and
+ 'sendemail.smtppass', but see also 'sendemail.identity'.
+ If not set, authentication is not attempted.
+
+--smtp-ssl::
+ If set, connects to the SMTP server using SSL.
+ Default is the value of the 'sendemail.smtpssl' configuration value;
+ if that is unspecified, does not use SSL.
+
--subject::
Specify the initial subject of the email thread.
Only necessary if --compose is also set. If --compose
CONFIGURATION
-------------
+sendemail.identity::
+ The default configuration identity. When specified,
+ 'sendemail.<identity>.<item>' will have higher precedence than
+ 'sendemail.<item>'. This is useful to declare multiple SMTP
+ identities and to hoist sensitive authentication information
+ out of the repository and into the global configuation file.
+
sendemail.aliasesfile::
To avoid typing long email addresses, point this to one or more
email aliases files. You must also supply 'sendemail.aliasfiletype'.

sendemail.smtpserver::
- Default smtp server to use.

+
+sendemail.smtpuser::
+ Default SMTP-AUTH username.

+ Boolean value specifying the default to the '--smtp-ssl' parameter.

+Creating an archive
+~~~~~~~~~~~~~~~~~~~
+
+`export-subst`
+^^^^^^^^^^^^^^
+
+If the attribute `export-subst` is set for a file then git will expand
+several placeholders when adding this file to an archive. The
+expansion depends on the availability of a commit ID, i.e. if
+gitlink:git-archive[1] has been given a tree instead of a commit or a
+tag then no replacement will be done. The placeholders are the same
+as those for the option `--pretty=format:` of gitlink:git-log[1],
+except that they need to be wrapped like this: `$Format:PLACEHOLDERS$`
+in the file. E.g. the string `$Format:%H$` will be replaced by the
+commit hash.

This hook is meant primarily for notification, and cannot affect
the outcome of `git-commit`.
+post-merge
+-----------
+
+This hook is invoked by `git-merge`, which happens when a `git pull`
+is done on a local repository. The hook takes a single parameter, a status
+flag specifying whether or not the merge being done was a squash merge.
+This hook cannot affect the outcome of `git-merge`.
+
+This hook can be used in conjunction with a corresponding pre-commit hook to
+save and restore any form of metadata associated with the working tree
+(eg: permissions/ownership, ACLS, etc). See contrib/hooks/setgitperms.perl
+for an example of how to do this.
