 # This is the configuration file for filetype detection and application
 # handling.  It's all in python; lines beginning with # are comments.
 #
-# Here, the class "CustomApplications" is defined as a subclass of the default
-# application handler class.  It is located at ranger/defaults/apps.py and
-# contains a whole lot of definitions.  You can just copy & paste them here.
+# Scroll down for a few examples.
+# ===================================================================
+# This system is based on things called MODES and FLAGS.  You can read
+# in the man page about them.  To remind you, here's a list of all flags.
+# An uppercase flag inverts previous flags of the same name.
+#     s   Silent mode.  Output will be discarded.
+#     d   Detach the process.  (Run in background)
+#     p   Redirect output to the pager
+#     w   Wait for an Enter-press when the process is done
+#     c   Run the current file only, instead of the selection
+#
+# To implement modes in this file, you can do something like:
+#     if context.mode == 1:
+#         <run in one way>
+#     elif context.mode == 2:
+#         <run in another way>
+#
+# To implement flags in this file, you could do this:
+#     context.flags += "d"
+# Another example:
+#     context.flags += "Dw"
+# ===================================================================
+# The methods are called with a "context" object which provides some
+# attributes that transfer information.  Relevant attributes are:
+#
+# mode -- a number, mainly used in determining the action in app_xyz()
+# flags -- a string with flags which change the way programs are run
+# files -- a list containing files, mainly used in app_xyz
+# filepaths -- a list of the paths of each file
+# file -- an arbitrary file from that list (or None)
+# fm -- the filemanager instance
+# popen_kws -- keyword arguments which are directly passed to Popen
+# ===================================================================
+# The return value of the functions should be either:
+# 1. A reference to another app, like:
+#     return self.app_editor(context)
+#
+# 2. A call to the "either" method, which uses the first program that
+# is installed on your system.  If none are installed, None is returned.
+#     return self.either(context, "libreoffice", "soffice", "ooffice")
+#
+# 3. A tuple of arguments that should be run.
+#     return "mplayer", "-fs", context.file.path
+# Since the tuple is flattened later, you can even put lists of files here:
+#     return "mplayer", "-fs", "-shuf", context.filepaths
+# This can, and will often be abbreviated with:
+#     return "mplayer", "-fs", "-shuf", context
