+# Musicfix is a music file renamer and tagger with consistency concerns.
+# It has a release-centered logic and gets data from www.discogs.com.
+# First configure the target music directory (mdir variable).
+# Next browse the site and locate your album. Change to the album's
+# directory. Ensure the files are ordered and provide the release id
+# to the program. Enjoy!
+
+# Dependencies:
+# System packages: taglib
+# Ruby gems: discogs-wrapper stringex taglib-ruby
+

+# [f]t: track title
+# [f]n: track number, may have letters (vinyls)
+# d: disc number
+# tn: track number counter
+# x: file extension in lowercase
