# filterfs

WIP.

The idea is to have a filesystem provide a 1:1 copy of a file (like `/dev/kbd`) to be available for reading
(opened in RO mode) and for filtering/rewriting (opened in RW mode).

Filtering is made by opening the `<file>filter` in RW mode by a separate program. Filters can be chained one
after the other by opening the file in specific order.
