+Capture and retrieve the last time a function was run.
+
+## Usage
+
+```js
+var lastRun = require('last-run');
+
+function myFunc(){}
+
+myFunc();
+// capture the run after (or before) calling the function
+lastRun.capture(myFunc);
+
+// retrieve the last run time
+lastRun(myFunc);
+//-> outputs the Date.now() when capture was called
+```
+
+## API
+
+__Note: this module uses a WeakMap shim, and throws on non-extensible functions on platforms that
+don't have a native WeakMap implementation__
+
+### lastRun(fn, [timeResolution]) => [Timestamp]
+
+Takes a function (`fn`) and returns a timestamp of the last time the function was captured.
+
+Returns undefined if the function has not been captured.
+
+The timestamp is always given in millisecond but the time resolution can be reduced (rounded down).
+The use case is to be able to compare a build time to a file time attribute.
+On node v0.10 or with file system like HFS or FAT, `fs.stat` time attributes like `mtime` precision is one second.
+
+Assuming `lastRun(fn)` returns 1426000001111, `lastRun(fn, 1000)` returns 1426000001000.
+
+The default time resolution is 1000 on node v0.10, 0 on node 0.11+ and iojs.
+More information at [`default-resolution`][default-resolution] and
+[undertaker PR #17][undertaker-17].
+
+### lastRun.capture(fn, [timestamp])
+
+Takes a function (`fn`) and captures the current timestamp with `Date.now()`.
+If passed the optional timestamp, captures that time instead of `Date.now()`.
+The captured timestamp can then be retrieved using the `lastRun` function.
+
+### lastRun.release(fn)
+
+Takes a function (`fn`) and removes the last run timestamp for it.
