generatejournal.hs NUMTXNS NUMACCTS ACCTDEPTH [--chinese|--mixed]
Outputs a dummy journal file with the specified number of
transactions, number of accounts, and account tree depth. By default
it uses only ascii characters, with --chinese it uses wide chinese
characters, or with --mixed it uses both. These files are used for
testing, benchmarking, profiling, etc.
This generates synthetic journal data for benchmarking & profiling.
It prints a dummy journal on stdout, with NUMTXNS transactions, one
per day, using NUMACCTS account names with depths up to ACCTDEPTH.
It will also contain NUMACCTS P records, one per day.
By default it uses only ascii characters, with --chinese it uses wide
chinese characters, or with --mixed it uses both.
