1.1.1 Configuration Management
</H2>
The main task of <SMALL>SCRAM</SMALL>&nbsp;is to ensure that all developers are working
with the same consistent set of external products, libraries,
environments and source codes. Configuration management methods ensure
that this is possible.
<DL>
<DT><STRONG><SMALL>EXTERNAL PRODUCTS CONFIGURATION</SMALL></STRONG></DT>
<DD>
<BR>
A requirement of any <SMALL>SCRAM</SMALL>&nbsp;managed project is an explicit
  statement, in the form of a special-purpose document, of all
  underlying products and versions of external libraries and other
  software products used. Each product must have a description
  document to inform <SMALL>SCRAM</SMALL>&nbsp;how it is to be used, to supply dependency
  information, set environmental variables, and give default system
  locations.  Such description documents can be maintained
  independently of <SMALL>SCRAM</SMALL>&nbsp;and imported into the project by
  <SMALL>SCRAM</SMALL>'s built-in URL downloading mechanism.
</DD>
<DT><STRONG><SMALL>COMMON CONFIGURATIONS</SMALL></STRONG></DT>
<DD>
<BR>
It is often the case that many projects need to share the same
  configuration in order that they can be inter-operable (e.g. two
  applications using the same database).  <SMALL>SCRAM</SMALL>&nbsp;thus provides a
  mechanism for importing independently maintained configuration
  documents automatically.
</DD>
<DT><STRONG><SMALL>SOURCE CODE CONTROL</SMALL></STRONG></DT>
<DD>
<BR>  <SMALL>SCRAM</SMALL>&nbsp;itself is not a code repository.  Any project must have
  access to one or more such repositories from which it can checkout
  the appropriate code into the appropriate place in the project
  structure. Currently, CVS is used for all source code management.
  Both source code and project configuration files are tagged with a
  CVS symbolic tag when ready for release.
</DD>
<DT><STRONG><SMALL>ENVIRONMENT CONTROL</SMALL></STRONG></DT>
<DD>
<BR>
The build and runtime environments are constructed automatically
  from the description documents of the required external products and
  the project-specific environment.
</DD>
