How to split animations via script in editor

I both love and hate asking and THEN finding. So, I ask to save time ;)

I found this script that works perfectly - you provide a text file named identically to the FBX, then reimport and bingo - all clips are created via the txt file. I'm pasting a modified version as there is one line that threw an obsolete error.

 // FbxAnimListPostprocessor.cs : Use an external text file to import a list of
 
 // splitted animations for FBX 3D models.
 //
 // Put this script in your "Assets/Editor" directory. When Importing or
 // Reimporting a FBX file, the script will search a text file with the
 // same name and the ".txt" extension.
 // File format: one line per animation clip "firstFrame-lastFrame loopFlag animationName"
 // The keyworks "loop" or "noloop" are optional.
 // Example:
 // 0-50 loop Move forward
 // 100-190 die
