+# If you run into problems with this script, please send me email
+
+# PURPOSE:
+# --------------------------
+# This is a wrapper script that tries to find the best parameters
+# for calling an underlying video player.  The outer layer determines
+# the best playback parameters, while the inner layer picks the best
+# player to call.
+
+# RATIONALE:
+# --------------------------
+# Default video playback options are not optimal on all hardware or
+# for all video types.  In addition, common video players do not
+# offer to bookmark video so that you can resume where you left off.
+# Both of these problems can be addressed by this wrapper.
+
+# PARAMETERS:
+# --------------------------
+# The same parameters you'd use for mplayer, some of which may be
+# translated automatically for use with smplayer.
+
+# FILES:
+# --------------------------
+# $mediafile, the file to play
+
+sub run () {
+    my $mediafile = @ARGV[$#ARGV];
+    my $player = &pick_player();
+
+    # mplayer evaluates configuration options in the following order, with
+    # later-evaluated options overriding earlier-evaluated ones, both within
+    # a given configuration location and between them:
+    # 1) system-wide configuration/profiles, /etc/mplayer/mplayer.conf
+    # 2) user-specific configuration/profiles, ~/.mplayer/config
+    # 3) commandline configuration parameters
+    # 4) file-specific configuration, ~/.mplayer/[filename].conf
+    # 5) any nonstandard configuration file, included via "-include" parameter
+    #
+    # This script's dynamic configuration options fall in at 2.5 above,
+    # so commandline options, file-specific configuration options,
+    # or a nonstandard configuration file will override the options that
+    # the script creates, but system-wide and user-specific configuration
+    # will be overridden by the dynamic configuration options.
+    #
+    # This is sub-optimal, as the easiest way for a user to compensate for
+    # a misfiring configuration rule would be to override it in a configuration
+    # file.  Instead, they will have to change the way they run this script.
