I've never seen any standard use of -s and -n. -H useally denotes the histogram output file. -n could possible be number of events, though I believe the -e option is more widely used for that. Anyway, I guess you used the BrAppOptionManager for all this, so there should be little problem, since one can simply do --help to get a list of options. But, and it's a question Flemming has raised before, perhaps we should agree on some standard meaning of various options. That will make life easier for all of us. Here's what I believe is the de facto standard, intermingled with my suggestions: -h --help b Show help (already in the manager, so standard) -V --version b Show version (already in the manager, so standard) -i --input s Single file input name (and not directroies) -o --output s Single file output name -H --histogram s Single file histogram output -I --input-directory s Where to find input files -F --max-files i Maximum number of input files (e.g., sequences) -v --verbose i Verbosity level -d --debug i Debug level -m --magnet s Magnet ASCII file (should go away soon) -g --geometry s Geometry ASCII file (should go away soon) -r --run i Run number -e --max-events i Max number of events -M --maindb-host s Main Database host -D --maindb-name s Main Database name -U --maindb-user s Main Database user [b = boolean, i = integer, s = string, f = float] There may be more options that we would want to standarise, and if you can think of some, please answer to this message. Please remember though, that we don't want standarised options for things like 'the adc gain in TOF1 slat 5, top tube'. Individual user/developers are then free to use the rest of the alphabet to define other options. For example could one think of things like -z --max-vertex-z f Maximum absolute value of primary vertex Z coord. -t --triggers s list of triggers to use. At some point, I'd like to make an option that is repeatable, so you could do ./myapp -t 1 -t 5 -t 6 ... and then get the list of values like tOption->GetValue(0); tOption->GetValue(1); tOption->GetValue(2); As it is now, any later occurence of the same option, will override the former. In particular, if you have a boolean option, which per default is true, and you specify it twice on the commandline, it will end up being true again.
