# The directory structure is 'doubled up' to avoid having 2 files: Readme.html

mkdir -p $PKG/usr/lib${LIBDIRSUFFIX}/gimp/2.0/plug-ins/export_layers

# Several 'zero length' files are added to the package which makepkg will complain

# Little in the way of docs to add here as the HTML docs are intended to
# be opened from within Gimp. They can still be read without Gimp being open by
# reading: /usr/lib${LIBDIRSUFFIX}/gimp/2.0/plug-ins/export_layers/Readme.html
