Music Library Maintainer
========================
MLM stands for Music Library Maintainer, and is a collection of small utilities
itended to, as its name implies, maintain a music library. It does so by reading
and writting a subset of Id3v2.4.0 tags, hencefort refered as the "standard
tags".
Standard tags
-------------
The standard tags are:
* Artist (`TPE1`)
* Title (`TIT2`)
* Album (`TALB`)
* Album band (`TPE2`), usually called "Album artist" in other suites
* Year (`TDRC`)
* Track (`TRCK`), including the total number of tracks on the disc
* Disc number (`TPOS`)
* Genre (`TCON`), the standard 148 genres from Id3v1
* Comment (`COMM`)
* Composer (`TCOM`)
* Original artist (`TOPE`)
* Album and artist picture (`APIC`)
Utilities
The utilities are:
* `mlm-gui`: A GNOME 3 program to edit standard tags, and perhaps playing or
reencoding the file containing them.
* `mlm-arranger`: Command line tool to arrange an MP3 file in a standard
hierarchical location.
* `mlm-analyze`: Command line tool to analyze all the Id3v2.4.0 tags (not only the
standard ones) in an MP3 file.
* `mlm-copy-tags`: Command line tool to copy the standard tags from an MP3 file to
another.
* `mlm-tags`: Command line tool to modify or print the standard tags of a file or
group of files.
* `mlm-verify`: Command line tool to verify that an MP3 file follows the MLM
standard.
All the command line utilities accept a `--help` argument that explains how to
use it, and include man pages.
