sftouch (3.0)
Applies the Unix command touch to binaries of RSF datasets in a directory.

        sftouch verb=n dir=. rec=n chk4nan=n
Will go down recursively in subdirectories. Current date and time is used.
Useful for determining disk leaks: Orphan binaries (those without headers) will
not be touched. You can remove them with commands such as:
find $DATAPATH -type f -mmin +15 -exec rm -f {} \;

bool chk4nan=n [y/n]
Check for NaN values. Expensive!!
string dir=.
Directory with files
bool rec=n [y/n]
Whether to go down recursively
bool verb=n [y/n]
Display what is wrong with the dataset
