 ('binary' encoding is not supported, stored as-is)
using actions/rule pair

rule a ( targets * : sources * : properties * )
{

}

actions a
{

}

sources contain not just file paths but something like <p.>some-path
using MATCH can remove <p.> substring but it looks like a hack
Are there any official ways to work with sources variable?
