.SYNOPSIS
|
||||
Rebuilds the 7zip-19.00 directory from original sources.
|

|
||||
.DESCRIPTION
|
||||
This script downloads 7-Zip 19.00 source code from 7-zip.org and merges it
|
||||
with the Nsis7z plugin files from the local archive to recreate the complete
|
||||
7zip-19.00 directory structure.
