rem Versioner script v1 haha

rem How this works:

rem Call verisoner.bat file.ext, it will create file.ext.version.txt

rem This file contains the revision count for the day. Don't mess with it.

rem Deleting it resets the day's revisions to 1.

rem .

rem It will also search for the string "~VERSION~" and replace it with

rem YYYY.MM.DD.VVV, where VVV = number of times this script was called today.

rem .

rem Automatically resets to 1 on new day. Output is STDOUT, so use something like

rem versioner.bat myfile.work.js > myfile.js if myfile.work.js has ~VERSION~ to be replaced.

rem .

rem Note: This script was designed for use with the "YYYY-MM-DD" "Short Date" format option enabled in Windows

rem Using with other schemes (such as DD/MM/YYYY or MM/DD/YYYY) may not work as intended.
