+; Example file for the OpenTTD Base Music replacement sets.
+; This file consists of basically two different parts:
+;  * metadata
+;  * information about the files/songs
+;
+; Metadata contains information about the name and version
+; of the music set.
+;
+; == Getting started ==
+; - you can't add comments after values
+; - you have to fill the MD5 checksum for each file
+; - you may not miss any of the metadata or files items
+; - `openttd -h` lists all music replacement sets it found to be correct
+; - `openttd -d grf=1` shows warnings/errors when parsing an .obm file
+; - `openttd -M <name>` starts OpenTTD with the given set (case sensitive)
+; - adding `musicset = <name>` to the misc section of openttd.cfg makes
+;   OpenTTD start with that sound set by default
+; - there is a command line tool for all platforms called md5sum that can
+;   create the MD5 checksum you need.
+; - all files specified in this file are search relatively to the path where
+;   this file is found, i.e. if the sound files are in a subdir you have
+;   to add that subdir to the names in this file to! It will NOT search for
+;   a file named like specified in here.
+
+[metadata]
+; the name of the pack, preferably less than 16 characters
+name         = example
+; the short name (4 characters), used to identify this set
+shortname    = XMPL
+; the version of this sound set (read as single integer)
+version      = 0
+; a fairly short description of the set
+; By adding '.<iso code>' you can translate the description.
+; Note that OpenTTD first tries the full ISO code, then the first
+; two characters and then uses the fallback (no '.<iso code>').
+; The ISO code matching is case sensitive!
+; So en_US will be used for en_GB if no en_GB translation is added.
+; As a result the below example has 'howdie' for en_US and en_GB but
+; 'foo' for all other languages.
+description  = foo
+description.en_US = howdie
+
+; The files section lists the files that replace songs.
+; The file names are case sensitive.
+; You can have empty file names; in that case no song will be loaded
+; for that 'entry'.
