 * **abbrev** - `(default: 7)` in the describe output, the object id of the hash is always abbreviated to N letters, by default 7. The typical describe output you'll see therefore is: `v2.1.0-1-gf5cd254`, where `-1-` means the number of commits away from the mentioned tag and the `-gf5cd254` part means the first 7 chars of the current commit's id `f5cd254`. **Please note that the `g` prefix is included to notify you that it's a commit id, it is NOT part of the commit's object id** - *this is default git bevaviour, so we're doing the same*. You can set this to any value between 0 and 40 (inclusive). 
 * **abbrev = 0** is a special case. Setting *abbrev* to `0` has the effect of hiding the "distance from tag" and "object id" parts of the output, so you endup with just the "nearest tag" (that is, instead `tag-12-gaaaaaaa` with `abbrev = 0` you'd get `tag`).
-* **dirty** - `(default: "")` when you run describe on a repository that's in "dirty state" (has uncommited changes), the describe output will contain an additional suffix, such as "-devel" in this example: `v3.5-3-g2222222-devel`. You can configure that suffix to be anything you want, "-DEV" being a nice example. The "-" sign should be inclided in the configuration parameter, as it will not be added automatically. If in doubt run git describe `--dirty=-my_thing` to see how the end result will look like.

 * **tags** - `(default: false)`
 * **long** - `(default: false)` git-describe, by default, returns just the tag name, if the current commit is tagged. Use this option to force it to format the output using the typical describe format. An example would be: `tagname-0-gc0ffebabe` - notice that the distance from the tag is 0 here, if you don't use **forceLongFormat** mode, the describe for such commit would look like this: `tagname`.
 * **always** - `(default: true)` if unable to find a tag, print out just the object id of the current commit. Useful when you always want to return something meaningful in the describe property.
