+>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
