 quickbench - quick & easy comparative benchmarking of command-line programs.
 (c) Simon Michael 2008-2016
 
-Can be used standalone as the quickbench executable, or
-in haskell project benchmark suites as the QuickBench library.
-
-This is based on the simplebench tool used in the hledger project.
-
-Old:
-
-Example:
-
-$ stack install
-$ quickbench --help
-...
-$ cat - >bench.tests
--f sample.ledger -s balance
--f ~/.ledger -s balance
-$ quickbench -v hledger "ledger --no-cache" ledger
-Using bench.tests

-Summary (best iteration):

-============================++=========+===================+=======
--f sample.ledger -s balance || 0.01 | 0.02 | 0.02
- -f ~/.ledger -s balance || 3.56 | 0.10 | 0.10
+This is a cleaned up successor to the simplebench benchmarking tool 
+from the hledger project. It can be used for general command-line 
+benchmarking (quickbench) or as a haskell library (QuickBench). 
+It is not smart or complicated like "bench" or criterion; it is 
+good for quick and dirty, exploratory, comparative measurements
+that you can understand at a glance.
