# Baut ALLE Extensions dieses Repos und aktualisiert das Repo-Listing (index.json).
#
# Ein Blender-Extension-Repo kann MEHRERE Extensions ausliefern: "server-generate"
# scannt den dist/-Ordner und listet jedes gefundene Zip. Dadurch liefert EINE
# URL in Blender sowohl den Rock- als auch den Tree-Generator.
#
# Aufruf:
#   .\build.ps1                         # nutzt "blender" aus dem PATH
#   .\build.ps1 -Blender "E:\...\blender.exe"
#
# Update-Workflow:
#   1. version im jeweiligen Manifest erhoehen (und bl_info in der .py)
#   2. .\build.ps1
#   3. git add -A; git commit -m "vX.Y.Z"; git push
#   4. In Blender: Preferences -> Get Extensions -> Repo -> "Check for Updates"
