+Function uses comma as the format separator for the `git log` command output. You can customise this by providing another character using `splitChar` option:
+
+```javascript
+var git = require('git-last-commit');
+
+git.getLastCommit(function(err, commit) {
+  // read commit object properties
+  console.log(commit);
+}, {splitChar: '|'});
