hrt.build in the current directory when scanning, it then creates a tempdir and executes the script there with $src set to the dir in the hrt root and $dst set to the tempdirthen it scans the tempdir as if it were at the location the original
hrt.build is inso you can use scripts to build subtrees!
it's still kinda broken. once i have it figured out i'll make the 0.1.7 release
