The new line syntax is:
[SRC] [rm|strip] DEST
This allows one to write things like this in atree:
bin/src
bin/src bin/dest
bin/src "bin/another file name"
rm dest/file
rm dest/dir # recursive
strip bin/src
bin/src strip bin/dest
Src and dest can contain spaces if full enclosed in double-quotes.
The strip command can be overridden using the STRIP env var.
