OpenWRT

===== Feeds =====
Reference: http://wiki.openwrt.org/doc/devel/feeds

Feed is a collection of packages which share a common location. Feeds may reside on a remote server, in a version control system, on the local filesystem, or in any other location addressable by a single name (path/URL) over a protocol with a supported feed method. Feeds are additional predefined package build recipes for OpenWrt Buildroot. 

The list of usable feeds is configured from the **feeds.conf** file (or **feeds.conf.default** when feeds.conf does not exist).

Example of <builroot dir>/**feeds.conf.default** contains:

<code>

src-svn   packages  svn://svn.openwrt.org/openwrt/packages
src-svn   xwrt      http://x-wrt.googlecode.com/svn/trunk/package
src-git   luci      git://nbd.name/luci.git
src-git   routing   git://github.com/openwrt-routing/packages.git

===== Package =====
Refer to http://wiki.openwrt.org/doc/devel/packages

Normally there are two files in a typical package directory in OpenWrt :


  *     package/Makefile
  *     package/patches

The **patches** directory is optional and typically contains bug fixes or optimizations to reduce the size of the executable.

The package **makefile** is the important item because it provides the steps actually needed to download and compile the package. 

===== Compile =====
