@echo off
rem Build the per-vendor system preset caches (one <vendor>.opc per vendor) by
rem running the generate_system_cache.exe dev tool against a profiles directory,
rem and make every profiles directory named on the command line ship-ready:
rem install the caches into it and delete the preset JSONs they replace, so a
rem build ships one copy of its presets instead of two.
rem
rem   scripts\build_preset_cache.bat [build_dir] [target_dir ...]
rem
rem   build_dir   defaults to "build"
rem   target_dir  profiles directories to ship into. Caches are generated into
rem               the source tree's resources\profiles, which is what every
rem               packaging step copies from; a target may be that same
rem               directory, which then only gets pruned.
rem
rem Shipping deletes, so it is a CI packaging step. A vendor's own <vendor>.json
rem goes along with its preset JSONs: the cache carries the vendor profile and
rem the version it was built at, so discovery, version checks and installing all
rem read it there. Only a vendor that has a cache is pruned, so non-vendor JSONs
rem (blacklist.json) are left alone, as are the vendor directories themselves -
rem thumbnails, covers and bed models still live there.
