-Thunar Advanced Properties (thunar-apr)
-=======================================
-
-Thunar-apr is an extension to Thunar, which provides additional pages for
-the file properties dialog, that are displayed for certain kinds of files:
-
- * Launcher/Link
- * Image
-
-The Launcher/Link page is displayed for .desktop files and allows users to
-easily edit the most important values (i.e. the command for a launcher and
-the URL for a link).
-
-The Image page is displayed for all kinds of image files supported by the
-GTK+ version used by Thunar. The page displays atleast the exact format of
-the image and the dimensions in pixels. If the plugin is build with support
-for libexif (you can explicitly disable this using the `--disable-exif'
-configure option) and the image file includes Exif tags, the most important
-Exif tags found in the image file will also be displayed.
-
-By default the thunar-apr extension will be installed, but as with every
-extension, it will slightly increase the resource usage of Thunar (this
-shouldn't be a real problem unless you're targeting an embedded system),
-and so you can pass `--disable-apr-plugin' to configure and the plugin
-won't be built and installed. Since it is an extension, you can also
-easily uninstall it afterwards by removing the thunar-apr.so file from
-the lib/thunarx-2/ directory of your installation (be sure to quit Thunar
-before removing files though).

-Thunar Simple Builtin Renamers (thunar-sbr)
-===========================================
-
-Thunar-sbr is an extension to Thunar, which includes a bunch of simple renamers
-for the bulk rename dialog:
-
- * Insert / Overwrite
- * Insert Date / Time
- * Numbering
- * Remove Characters
- * Search & Replace
- * Uppercase / Lowercase
-
-By default the thunar-sbr extension will be installed, but as with every
-extension, it will slightly increase the resource usage of Thunar (this
-shouldn't be a real problem unless you're targeting an embedded system), and so
-you can pass `--disable-sbr-plugin' to configure and the plugin won't be built
-and installed. Since it is an extension, you can also easily uninstall it
-afterwards by removing the thunar-sbr.so file from the lib/thunarx-2/ directory
-of your installation (be sure to quit Thunar before removing files though).
-
-
-Regular Expressions
--------------------
-
-The "Search & Replace" renamer can be built with support for regular ex-
-pressions using the Perl-compatible regular expression (PCRE) library
-version 6.0 or above. The reasons to use PCRE instead of the POSIX regular
-expressions, that are part of the system C library, are:
-
- * PCRE supports UTF-8, which Thunar uses internally for all user visible
-   texts (be sure to enable this when installing PCRE using the --enable-utf8
-   configure switch).
- * PCRE uses a more consistent syntax, which is easier to understand for
-   most people.

-Thunar Sendto Email (thunar-sendto-email)
-=========================================
-
-Thunar-sendto-email is an extension to Thunar, which adds an additional entry
-to the "Send To" sub menu, named "Mail Recipient", that starts the mail composer
-and attaches the selected files (using the exo-open mechanism).
-
-The extension uses the zip command to compress folders prior to sending them
-to the mail client, since most mail clients cannot handle directories as at-
-tachments. For regular files, larger than 200KiB, the extension prompts the
-user whether to compress the files (using the zip command) prior to sending
-them to the mail client.

-Thunar Trash Panel Applet (thunar-tpa)
-======================================
-
-Thunar-tpa is an extension for the Xfce Panel, which enables users to add a
-trash can to their panel, that
-
- * displays the current state of the trash can
- * can move files to the trash by dropping them on the trash icon
- * can empty the trash can
- * can open the trash can
-
-In order to build and install this plugin, you will need to have the xfce4-panel
-development headers and libraries installed (the appropriate package is usually
-called xfce4-panel-dev or xfce4-panel-devel). In addition, you'll need to have
-D-BUS 0.34 or above installed and Thunar must be built with D-BUS support.
-
-
-How does it work?
-=================
-
-To avoid running several desktop processes that all monitor and manage the
-trash can by itself, and thereby create an unnecessary maintaince and resource
-overhead, the trash applet simply connects to Thunar via D-BUS to query the
-state of the trash and send commands to the Trash.
-
-The trash applet is not limited to Thunar, but can work with any file manager
-that implements the org.xfce.Trash interface and owns the org.xfce.FileManager
-service. See the thunar-tpa-bindings.xml file for a details about the inter-
-face.
