I didn't make this tool, I'm just the one who uploaded it.

Version 1.3 was released on March 4th 2004.

Heres an extract from the readme:



SUMMARY
This is a helper utility for the The Elder Scrolls: Morrowindgame. It can perform following functions:

• Remove unnecessary data from ESM/ESP files (including GMST entries), significantly reducing number of conflicts between different mods.
  
  
• Merge leveled lists for all active plugins, eliminating leveled list conflicts (this function was intended to replace Horatio's Leveled List Merger).
  
  
• Merge changes done to the various TES objects and dialog entries.
  
• Generate detailed conflict report or the given list of plugins.
  
• Manage list of currently active plugins with possibility to update ESP file header (version and master file sizes) and to change plugin loading order.
  
  
• One-click “JUST FIX IT!” button that automatically executes a set of tasks to reduce number of conflicts between active plugins as much as possible
  without any user interaction.
