# CADdy installer - links this folder into FreeCAD's Mod directory.
#
# No admin rights needed: a junction (/J) does not require elevation,
# a symbolic link (/D) would. That is why a junction is used.
#
# Nothing is copied, it is LINKED. There is one source: this folder.
# After "git pull", FreeCAD loads the new version on its next start.

#     .\install.ps1 -Force                       # replace an existing link
#
# NOTE: keep this file PURE ASCII. Windows PowerShell 5.1 reads a .ps1
# without BOM in the ANSI code page; non-ASCII characters (accented letters,
# long dashes) make the script fail to parse.
