A small windows batch script you can include with your maps to make installation easier. Only required for Portal 2 maps that use custom particles, as the per-map manifests work in Portal 1.

Usage: edit the script with notepad. Find the line that looks like so:

    echo    "file"      "particles/impact_fx.pcf" >> particles_manifest.txt

Replace "particles/impact_fx.pcf" with the name of your particle system. Include it in the map zip, place it in the particles folder and tell users to run it before playing the map.

Not in portal 2, unfortunately.
