Examples:
doall 'run/*' # no arguments
doall -o foo.png 'run/*' # arguments for plscan
doall -a 1 -- -o foo.png 'run/*' # arguments for evscan and plscan
- usrp/doall: added usage()
- usrp/doall: arguments before -- are passed to evscan
- usrp/doall: new script to directly evaluate and plot data sets
- usrp/fft.c (fft_complex): don't square the magnitude
- usrp/plscan: if an argument name has the form title=name, use "name" as
the file name and "title" as the title
