Subject: Enable configuration files in /etc/laconica/
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=74bf2bf672b147888a42fafd7ae5d86c600cf3a8;p=quix0rs-gnu-social.git

+Starting with version 0.7.1, you can put config files in the
+/etc/laconica/ directory on your server, if it exists. Config files
+will be included in this order:
+
+* /etc/laconica/laconica.php - server-wide config
+* /etc/laconica/<servername>.php - for a virtual host
+* /etc/laconica/<servername>_<pathname>.php - for a path
+* INSTALLDIR/config.php - for a particular implementation
+
 Almost all configuration options are made through a two-dimensional
 associative array, cleverly named $config. A typical configuration
 line will be:
