+### This file controls the configuration of the svnserve daemon, if you
+### use it to allow access to this repository.  (If you only allow
+### access through http: and/or file: URLs, then this file is
+### irrelevant.)
+
+### Visit http://subversion.apache.org/ for more information.
+
+[general]
+### The anon-access and auth-access options control access to the
+### repository for unauthenticated (a.k.a. anonymous) users and
+### authenticated users, respectively.
+### Valid values are "write", "read", and "none".
+### Setting the value to "none" prohibits both reading and writing;
+### "read" allows read-only access, and "write" allows complete 
+### read/write access to the repository.
+### The sample settings below are the defaults and specify that anonymous
+### users have read-only access to the repository, while authenticated
+### users have read and write access to the repository.
+# anon-access = read
+# auth-access = write
+### The password-db option controls the location of the password
+### database file.  Unless you specify a path starting with a /,
+### the file's location is relative to the directory containing
+### this configuration file.
+### If SASL is enabled (see below), this file will NOT be used.
+### Uncomment the line below to use the default password file.
+# password-db = passwd
+### The authz-db option controls the location of the authorization
+### rules for path-based access control.  Unless you specify a path
+### starting with a /, the file's location is relative to the
+### directory containing this file.  The specified path may be a
+### repository relative URL (^/) or an absolute file:// URL to a text
+### file in a Subversion repository.  If you don't specify an authz-db,
+### no path-based access control is done.
+### Uncomment the line below to use the default authorization file.
+# authz-db = authz
+### The groups-db option controls the location of the groups file.
+### Unless you specify a path starting with a /, the file's location is
+### relative to the directory containing this file.  The specified path
+### may be a repository relative URL (^/) or an absolute file:// URL to a
+### text file in a Subversion repository.
+# groups-db = groups
+### This option specifies the authentication realm of the repository.
+### If two repositories have the same authentication realm, they should
+### have the same password database, and vice versa.  The default realm
+### is repository's uuid.
+# realm = My First Repository
+### The force-username-case option causes svnserve to case-normalize
+### usernames before comparing them against the authorization rules in the
+### authz-db file configured above.  Valid values are "upper" (to upper-
+### case the usernames), "lower" (to lowercase the usernames), and
+### "none" (to compare usernames as-is without case conversion, which
+### is the default behavior).
+# force-username-case = none
+### The hooks-env options specifies a path to the hook script environment 
+### configuration file. This option overrides the per-repository default
+### and can be used to configure the hook script environment for multiple 
+### repositories in a single file, if an absolute path is specified.
+### Unless you specify an absolute path, the file's location is relative
+### to the directory containing this file.
+# hooks-env = hooks-env
+
+[sasl]
+### This option specifies whether you want to use the Cyrus SASL
+### library for authentication. Default is false.
+### This section will be ignored if svnserve is not built with Cyrus
+### SASL support; to check, run 'svnserve --version' and look for a line
+### reading 'Cyrus SASL authentication is available.'
+# use-sasl = true
+### These options specify the desired strength of the security layer
+### that you want SASL to provide. 0 means no encryption, 1 means
+### integrity-checking only, values larger than 1 are correlated
+### to the effective key length for encryption (e.g. 128 means 128-bit
+### encryption). The values below are the defaults.
+# min-encryption = 0
+# max-encryption = 256
