| | | `-----------------------'
File to test ----' | | |
| | `- options

`--- optional prior output to diff
Do a cache-grind performance analysis of the sqlite3.c file named and
write the results into the output file. The ".txt" is appended to the
output file (and diff-file) name if it is not already present. If the
diff-file is specified then show a diff from the diff-file to the new
output.
Other options include:
--dryrun Show what would happen but don't do anything
--help Show this help screen
--lean "Lean" mode.
--lookaside N SZ Lookahead uses N slots of SZ bytes each
--pagesize N Use N as the page size
