+
+A preset file contains a sequence of @var{option=value} pairs, one for
+each line, specifying a sequence of options which can be specified also on
+the command line. Lines starting with the hash ('#') character are ignored and
+are used to provide comments. Empty lines are also ignored. Check the
+@file{ffpresets} directory in the Libav source tree for examples.
+
+Preset files are specified with the @code{pre} option, this option takes a
+preset name as input.  Avconv searches for a file named @var{preset_name}.avpreset in
+the directories @file{$AVCONV_DATADIR} (if set), and @file{$HOME/.avconv}, and in
+the data directory defined at configuration time (usually @file{$PREFIX/share/avconv})
