# Random db tester.
# Usage: dbscript file numops min_del max_add key_avg data_avgdups
# method: method (we pass this in so that fixed-length records work)
# file: db file on which to operate
# numops: number of operations to do
# ncurs: number of cursors
# min_del: minimum number of keys before you disable deletes.
# max_add: maximum number of keys before you disable adds.
# key_avg: average key size
# data_avg: average data size
# dups: 1 indicates dups allowed, 0 indicates no dups
# errpct: What percent of operations should generate errors
# seed: Random number generator seed (-1 means use pid)
