+# dfmd
+
+A small utility daemon to handle "open containing folder" activities in various
+software.
+
+🦊
+
+## Dependencies
+
+- DBus
+- xdg-open as the default handler
+
+## Building
+
+```
+cargo build --release
+```
+
+## Configuration
+
+Use the DFMD_*_PROGRAM environment variables. `%ARGS%` is substituted with a
+list of input files.
+
+### Default handler programs
+
+```
+DFMD_FOLDER_PROGRAM: echo %ARGS% | xargs -n1 xdg-open
+DFMD_ITEMS_PROGRAM: echo %ARGS% | xargs -d " " -I {} sh -c 'p="{}"; echo "${p%/*}"' | xargs -n1 xdg-open
+DFMD_PROPERTIES_PROGRAM: echo %ARGS% | xargs -n1 xdg-open
+```
+
+## Autostart
+
+Create a DBus service in
+`$XDG_DATA_HOME/dbus-1/services/org.freedesktop.FileManager1.service`.
+
+(The default directory for `XDG_DATA_HOME` is `$HOME/.local/share/`)
+
+```
