+Database Backend
+----------------
+
+git-cvsserver uses one database per git head (i.e. CVS module) to
+store information about the repository for faster access. The
+database doesn't contain any persitent data and can be completly
+regenerated from the git repository at any time. The database
+needs to be updated (i.e. written to) after every commit. That
+means that even if you offer only read access (e.g. by using
+the pserver method), git-cvsserver should have write access to
+the database to work reliably (otherwise you need to make sure
+that the database if up-to-date all the time git-cvsserver is run).
+
+By default it uses SQLite databases in the git directory, named
+`gitcvs.<module_name>.sqlite`. Note that the SQLite backend creates
+temporary files in the same directory as the database file on
+write so it might not be enough to grant the users using
+git-cvsserver write access to the database file without granting
+them also write access to the directory.
+
+You can configure the database backend with the following
+configuration variables:
+
+Configuring database backend
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+git-cvsserver uses the Perl DBI module. Please also read
+its documentation if changing these variables, especially
+about `DBI->connect()`.
+
+gitcvs.dbname::
+ Database name. The exact meaning depends on the
+ used database driver, for SQLite this is a filename.
+ Supports variable substitution (see below). May
+ not contain semicolons (`;`).
+ Default: '%Ggitcvs.%m.sqlite'
+
+gitcvs.dbdriver::
+ Used DBI driver. You can specify any available driver
+ for this here, but it might not work. cvsserver is tested
+ with 'DBD::SQLite', reported to work with
+ 'DBD::Pg', and reported *not* to work with 'DBD::mysql'.
+ Please regard this as an experimental feature. May not
+ contain double colons (`:`).
+ Default: 'SQLite'
+
+gitcvs.dbuser::
+ Database user. Only useful if setting `dbdriver`, since
+ SQLite has no concept of database users. Supports variable
+ substitution (see below).
+
+gitcvs.dbpass::
+ Database password. Only useful if setting `dbdriver`, since
+ SQLite has no concept of database passwords.
+
+All variables can also be set per access method, see <<configaccessmethod,above>>.
+
+Variable substitution
+^^^^^^^^^^^^^^^^^^^^^
+In `dbdriver` and `dbuser` you can use the following variables:
+
+%G::
+ git directory name
+%g::
+ git directory name, where all characters except for
+ alpha-numeric ones, `.`, and `-` are replaced with
+ `_` (this should make it easier to use the directory
+ name in a filename if wanted)
+%m::
+ CVS module/git head name
+%a::
+ access method (one of "ext" or "pserver")
+%u::
+ Name of the user running git-cvsserver.
+ If no name can be determined, the
+ numeric uid is used.
