+This plugin allows to display command's execution time in a very nonintrusive way.
+
+Timer can be tuned by these two variables:
+* `TIMER_PRECISION` allows to control number of decimal places (default `1`)
+* `TIMER_FORMAT` allows to adjust display format (default `'/%d'`)
+
+Sample session:
+
+    me@here:~$ sleep 1                                         /1.0s
+    me@here:~$ sleep 73                                     /1m13.0s
+    me@here:~$ TIMER_FORMAT='[%d]'; TIMER_PRECISION=2        [0.00s]
+    me@here:~$ head -c50 < /dev/urandom | hexdump
