+The directory "db" contains a Berkeley DB environment.

+# [general]
+### These options control access to the repository for unauthenticated
+### and authenticated users.  Valid values are "write", "read",
+### and "none".  The sample settings below are the defaults.
+# anon-access = read
+# auth-access = write
+### This option controls the location of the password database.  This
+### path may be relative to the conf directory.  There is no default.
+### The format of the password database is:
+### [users]
+### USERNAME = PASSWORD
+# password-db = passwd
+### 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 the path to the repository, relative to the server's repository
+### root.
+# realm = My First Repository

+# Because the commit has already completed and cannot be undone,
+# the exit code of the hook program is ignored.  The hook program
+# can use the 'svnlook' utility to help it examine the
+# newly-committed tree.
+#
+# On a Unix system, the normal procedure is to have 'post-commit'
+# invoke other programs to do the real work, though it may do the
+# work itself too.
+#
+# Note that 'post-commit' must be executable by the user(s) who will
+# invoke it (typically the user httpd runs as), and that user must
+# have filesystem-level permission to access the repository.
