Filesystem structure of a Horde application

This information is valid for Horde 3 only. See Doc/Dev/Filesystem for Horde 4 and later.

Each Horde application has a common filesystem structure. This helps organizing the several components of the application and simplifies working with unknown applications.

These are the directories available in every Horde application:
 || Directory || Content ||
 || / || Base directory with the controller scripts called by the browser ||
 || config/ || Configuration files ||
 || docs/ || Administrator documentation ||
 || lib/ || Application-specific library files ||
 || locale/ || Compiled translations and help files ||
 || po/ || Translations ||
 || scripts/ || CLI scripts for setup and maintenance ||
 || scripts/sql/ || SQL scripts for setup ||
 || scripts/upgrades/ || CLI and SQL scripts for upgrades ||
 || templates/ || Template files ||
 || themes/ || Base stylesheet and theme directories ||
 || themes/graphics/ || Icons ||
Usually there are more directories, depending on the application:


    If there are many controller scripts for an application, they may be grouped into directories under the base directory.
    The lib/ directory has many levels of subdirectories. See Doc/Dev/FrameworkH3 for details.
    The locale/ directory has a subdirectory for each locale, e.g. locale/de_DE/. These subdirectories contain the translated help file help.xml and the directory LC_MESSAGES/ which contains the actual, compiled translation, e.g. imp.mo.
    The scripts/ directory may contain other directories for special purposes, e.g. ldap/.
    The templates/ directory groups all templates for a single controller script into one subdirectory. All templates for a script called list.php are inside templates/list/ for example.
    Each theme has a subdirectory, e.g. themes/bluewhite/; if a theme provides its own icon set, the icons are inside a graphics/ subdirectory, e.g. themes/bluewhite/graphics/.
    Some applications have sub-sets of their icons grouped into subdirectories, e.g. themes/graphics/flags/.
