+"The dependency system allows individual programs to make use of shared "
+"elements in the system such as libraries. It simplifies placing infrequently "

+"The first step to understanding the dependency system is to grasp the "

+"mail transport agent such as sendmail, exim or qmail. It is not possible to "
+"have two mail transport agents installed because both need to listen to the "

+"As an added complication there is the possibility for a package to pretend "
+"to be another package. Consider that exim and sendmail for many intents are "

+"the package system has a way for them to declare that they are both "
+"mail-transport-agents. So, exim and sendmail both declare that they provide "
