REM  LEGO Instructions Manager - Instruction Fetcher + Logging installer
REM
REM  RUN THIS FROM THE FOLDER YOU EXTRACTED THE UPDATE INTO, not from your
REM  LIM install - the two cannot be the same folder.
REM
REM  Copies 22 named files into an existing LIM install, backing up every
REM  file it replaces first. Whole directories are never copied, so your
REM  uploads and database are not involved.
REM
REM  Usage:   install_instruction_fetcher.bat [target]
REM  Default target: E:\LIM
