->A source distribution of <SPAN
-CLASS="PRODUCTNAME"
->eCos</SPAN
-> consists of a number of
- packages, such as the kernel, the C library, and the
- µITRON subsystems. These are
- individually versioned in the tree structure of the source
- code, to support distribution on a per-package basis and to
- support third party packages whose versioning systems might be
- different. The <SPAN
-CLASS="PRODUCTNAME"
->eCos</SPAN
-> <SPAN
-CLASS="APPLICATION"
->Package
- Administration Tool</SPAN
-> is used to manage the
- installation and removal of packages from a variety of sources
- with potentially multiple versions.</P
-><P
->The presence of the version information in the source tree
- structure might be a hindrance to the use of a separate source
- control system such as <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->CVS</I
-></SPAN
-> or
- <SPAN
-CLASS="emphasis"
-><I
-CLASS="EMPHASIS"
->SourceSafe</I
-></SPAN
->. To work
- in this way, you can rename all the version components to some
- common name (such as “current”) thus unifying the
- structure of source trees from distinct <SPAN
-CLASS="PRODUCTNAME"
->eCos</SPAN
-> releases.</P
-><P
->The <SPAN
-CLASS="PRODUCTNAME"
->eCos</SPAN
-> build system will treat any such name as just another
-version of the package(s), and support building in exactly the same
-way. However, performing this rename invalidates any existing build
-trees that referred to the versioned source tree, so do the rename
-first, before any other work, and do a complete rebuild afterwards.</P
