13 | |
---|
14 | <para>CLFS includes many packages, a number of which might not necessarily |
---|
15 | be required for a "minimal" system, but still considered very useful. The |
---|
16 | purpose of this page is to list the reasoning for each package's inclusion |
---|
17 | in the book.</para> |

25 | developers, as well as anyone who wants to install packages that don't |
---|
26 | come with a configure script, such as some of the packages in CBLFS.</para> |
