" make-data \n"
" \n"
" DESCRIPTION: \n"
" \n"
" Generate ASCII test files for testing ASSA log server. \n"
" An optional input file is repetitevly copied into the output file \n"
" until the desired output file size is reached. If an input file \n"
" option is omitted, MakeData.cpp is used instead. \n"
" \n"
" USAGE: \n"
" \n"
" shell> make-data [OPTIONS] -o <name> -n <size> \n"
" \n"
" EXAMPLE: \n"
" \n"
" shell> make-data --output-file 1Mb -n 1 \n"
" \n"
" Create ASCII file of 1 megabyte long with name 1Mb by repetetively \n"
" copying MakeData.cpp. \n"
" \n"
" OPTIONS: \n"
" \n"
" -o, --output-file NAME - Name of the output data file \n"
" -i, --input-file NAME - Name of the input data file (optional) \n"
" -n, --size NUM - Output file size (in megabytes) \n"
" \n"
" -D, --log-file NAME - Write debug to NAME file \n"
" -d, --log-stdout - Write debug to standard output \n"
" -z, --log-size NUM - Maximum size debug file can reach (dfl: is 10Mb) \n"
" \n"
" -m, --mask MASK - Mask (default: ALL = 0x7fffffff) \n"
" -h, --help - Print this messag \n"
" -v, --version - Print version number \n";
