Editing Package manager (section)

===Front-ends for locally compiled packages===
[[System administrator]]s may install and maintain software using tools other than package management software. For example, a local administrator may [[download]] unpackaged source code, compile it, and install it. This may cause the state of the local system to fall out of [[synchronization (computer science)|synchronization]] with the state of the package manager's [[database]]. The local administrator will be required to take additional measures, such as manually managing some dependencies or integrating the changes into the package manager.

There are tools available to ensure that locally compiled packages are integrated with the package management. For distributions based on .deb and [[RPM Package Manager|.rpm]] files as well as [[Slackware|Slackware Linux]], there is [[CheckInstall]], and for recipe-based systems such as [[Gentoo Linux]] and hybrid systems such as [[Arch Linux]], it is possible to write a recipe first, which then ensures that the package fits into the local package database.{{Citation needed|date=July 2007}}
