# CONTROL files
Each port has some static metadata in the form of a `CONTROL` file. This file uses the same syntax and a subset of the fields from [the Debian `control` format][debian].
Field names are case-sensitive.
[debian]: https://www.debian.org/doc/debian-policy/ch-controlfields.html
## Recognized fields
## Source Paragraph
### Source
The first paragraph appearing in a `CONTROL` file is the Source paragraph, which defines the core attributes of the package (name, version, and so on).
### Example:
```no-highlight
Source: vtk
Version: 8.1.0-1
Description: Software system for 3D computer graphics, image processing, and visualization
Build-Depends: zlib, libpng, tiff, libxml2, jsoncpp, glew, freetype
```
### Recognized fields
#### Source
The name of the port.
### Version
#### Version
The port version.
This field should be an alphanumeric string which may also contain `.`, `_`, or `-`. No attempt at ordering versions is made; all versions are treated as bitstrings and are only evaluated for equality.

### Description
#### Description
A description of the library
The first sentence of the description should concisely describe the purpose and contents of the library. Then, a larger description including the library's "proper name" should follow.
### Maintainer

### Build-Depends
#### Build-Depends
The list of dependencies required to build and use this library.

Build-Depends: zlib (windows), openssl (windows), boost (windows), websocketpp (windows)
```
## Feature Paragraphs
After the Source Paragraph, `CONTROL` files can list zero or more Feature Paragraphs which declare features.
### Example:
```no-highlight
Source: vtk
Version: 8.1.0-1
Description: Software system for 3D computer graphics, image processing, and visualization
Build-Depends: zlib, libpng, tiff, libxml2, jsoncpp, glew, freetype
Feature: mpi
Description: MPI functionality for VTK
Build-Depends: msmpi, hdf5[parallel]
```
### Recognized fields
#### Feature
The name of the feature.
#### Description
A description of the feature
#### Build-Depends
The list of dependencies required to build and use this feature.
All dependencies from selected features are unioned together to produce the final dependency set for the build. This field follows the same syntax as `Build-Depends` in the Source Paragraph.
