|

| 21 | <para>Most information about these packages (especially the descriptions of
|
|---|
| 22 | them) come from the man pages of those packages. We do not include
|
|---|
| 23 | the entire man page, but just some key elements to make it possible to
|
|---|
| 24 | understand what a program does. To get information on all details of a program,
|
|---|
| 25 | please refer to its man page or info page.</para>
|
|---|
| 26 |
|
|---|
| 27 | <para>Certain packages are documented in more depth
|
|---|
| 28 | than others, because we just happen to know more about certain
|
|---|
| 29 | packages than about others. If you think anything should be added to the
|
|---|
| 30 | following descriptions, please don't hesitate to email the mailing
|
|---|
| 31 | lists. We intend that the list should contain an in-depth description
|
|---|
| 32 | of every package installed, but we can't do it without help.</para>
|
|---|
| 33 |
|
|---|
| 34 | <para>Please note that currently only what a package does is described and not
|
|---|
| 35 | why it needs to be installed. This may be added later.</para>
|
|---|
| 36 |
|
|---|
| 37 | <para>Also listed are all of the installation dependencies for all the
|
|---|
| 38 | packages that are installed in this book. The listings will include
|
|---|
| 39 | which programs from which packages are needed to successfully compile
|
|---|
| 40 | the package to be installed.</para>
|
|---|
| 41 |
|
|---|
| 42 | <para>These are not running dependencies, meaning they don't tell you
|
|---|
| 43 | what programs are needed to use that packages programs. Just the ones
|
|---|
| 44 | needed to compile it.</para>
|
|---|
| 45 |
|
|---|
| 46 | <para>The dependency list can be, from time to time, outdated in regards
|
|---|
| 47 | to the currently used package version. Checking dependencies takes quite a
|
|---|
| 48 | bit of work, so they may lag behind a bit on the package update. But
|
|---|
| 49 | often with minor package updates, the installation dependencies hardly
|
|---|
| 50 | change, so they'll be current in most cases. When we upgrade to a major
|
|---|
| 51 | new release, we'll make sure the dependencies are checked too.</para>
