[![Average time to resolve an issue](http://isitmaintained.com/badge/resolution/kou1okada/apt-cyg.svg)](http://isitmaintained.com//project/kou1okada/apt-cyg "Average time to resolve an issue")


**`apt-cyg`** is your friendly [Cygwin](http://cygwin.com/) package manager. The syntax is similar to *apt-get* and is a feature improved wrapper to the native Cygwin `setup.exe`.


| STATUS: | Version | Date | Maintained? |
|:------- |:------- |:---- |:----------- |
| Working | `1.0.58` | 2018-11-22 | YES |

---

#### Forks on the github

See [other_forks.md](other_forks.md)

#### Todo

- [ ] Support multi mirrors: Cygwin setup can use multi mirrors. They are recorded at last-mirror section in '/etc/setup/setup.rc'. It's useful for using [Cygwinports](http://cygwinports.org/).
- [ ] Support upgrade: But maybe, busy resources can not be upgraded, and rebase problem will happen. Cygwin setup resolves by replacing them at next reboot.
- [ ] Support dependency check for remove subcommand.

#### Known Problems

For older known problems see: [**`known problems`**](known_problems.md)
