+--   Added a "matching '•'" variant of the script at the request of blumpy

+--   # Toggle visibility of empty non-folder tracks
+--
+--   This script toggles the TCP and MCP visibility of tracks matching all of the
+--   following criteria:
+--
+--   - Track has no FX on it
+--   - Track does not contain any media item
+--   - Track has no envelopes
+--   - Track is not a folder
+--   - Track is not record armed
+--
+--   A variant of the script is provided which additionally requires tracks to
+--   contain the character • (bullet) in their name. Custom variants can be
+--   created by copying the script with the desired track name search string
+--   between the apostrophes in the filename.
