- <para>One solution might be to integrate it into our project completely
- (e.g. in a <filename>lib</filename> folder) and put the whole project
- under version control (<xref linkend="glo_Soft_Git"/>, <xref
- linkend="glo_Svn"/>). On the other hand this just bloats our project
- with external (library) dependencies.</para>
-
- <para>Maven helps us to easily manage external dependencies. The idea is
- to keep them in centralized repositories for download and add meta
- information like a package name, a package group name and a version
