== The rationale behind maemo-release ==

The maemo-release package seeks to address the situation wherein a source package is forked into gregale/bora/chinook/diablo/fremantle versions of itself because one set of Build-Depends does not work for all distributions.

Example: Fremantle provides libgstfarsight0.10-dev, whereas previous distributions do not. pidgin needs to Build-Depend on it for voice/video support to be compiled in during the build process. However, the libgstfarsight0.10-dev package does not exist in any previous distribution.

This results in having to provide a different debian/control file for the various distributions, which in turn forces one to make a different debian/changelog file for the various distributions. At this point, different distributions have different source packages.

To prevent this one reason for forking the source package, we need the maemo-release package. Then, knowing which distribution(s) contain a needed package foo, we can create an appropriate debian/control entry.

Example: Suppose Bora and Diablo contain package foo, but the other distributions do not. The corresponding debian/control Build-Depends entry will be:

<code>
Build-Depends: package1-dev,
package2-dev,
...,
foo | maemo-version (= 1.0.0) | maemo-version (= 3.0.0) | maemo-version (= 5.0.0),
...,
packagen-dev
</code>

This way you can describe intervals of distributions wherein a certain package has become available. Examples:

{|style="border:1px solid;"
|-
!align="center"|   (1.0.0) Gregale  
!align="center"|   (2.0.0) Bora  
!align="center"|   (3.0.0) Chinook  
!align="center"|   (4.0.0) Diablo  
!align="center"|   (5.0.0) Fremantle  
|-
|colspan="5" style="border:1px solid;" | Example: <code>foo | maemo-release (< 3.0.0)</code>
|-
| align="center" style="background:red; color:white" colspan="2" | foo is absent
| align="center" style="background:green; color:white" colspan="3" | foo is present
|-
|-

|-
