==========================
Improved
--------
- `--sort LIMIT:FIELD:DIRECTION` option for sorting and limiting aggregate
queries.
- Added long options such as `--output` for `-o` and `--filter` for `-f`.
- Added aggregate functions `var()` (population variance) and `dev()` (standard
deviation)
- Experimental `--x-tmp-dir=/tmp` option when you are running aggregates over
large (> 10 million lines) logs. If you've run out of memory trying to run a
logrep query, try this option. If not, don't use it.
- More cleanups, getting rid of special cases, etc.
- Several speedups, bugfixes, etc.
