rem assumes we're being run like this:
rem %0 ssh://hostname/
rem we strip out the ssh:// part and the trailing slash
rem and then send the rest to putty
rem Note: we can't handle port numbers or anything after
rem the slash appended to the hostname.

rem Set this to your putty installation.

rem strip trailing slash (always appended by shell)
