<P>
This file contains specialized markup tags which encode information readable
by the LON-CAPA make/build process.  This is meant to be "the master file" which
encodes all necessary configuration information to the associated make process.
The format of these tags is:
<BR>&lt;LONCAPA TYPE=type [otherparameters]&gt;
</P>
<P>
Here are examples of all the different types of LONCAPA make/build tags.
<BR>&lt;LONCAPA TYPE=LOCATION DIST="redhat6.2" SOURCE="loncom/modules/TexConvert/tthperl/lontex.pm" TARGET="home/httpd/lib/perl/Apache/lontex.pm" CATEGORY="handler"&gt;
<BR>&lt;LONCAPA TYPE=DIRECTORY DIST="redhat6.2" TARGET="home/httpd/lib/perl/Apache" CATEGORY="writeable by server"&gt;
<BR>&lt;LONCAPA TYPE=OWNERSHIP DIST="redhat6.2" CATEGORY="setuid" CHMOD="6755" CHOWN="root:root"&gt;
<BR>&lt;LONCAPA TYPE=RPM NAME="Vendor" VALUE="Laboratory for Instructional Technology Education, Division of Science and Mathematics Education, Michigan State University.">
</P>
<P>
The NAME tags associated with TYPE=RPM are:
<UL>
<LI>Summary
<LI>Name
<LI>Version
<LI>Release
<LI>Vendor
<LI>BuildRoot
<LI>Copyright
<LI>Group
<LI>Source
<LI>AutoReqProv
<LI>description
<LI>pre
</UL>
</P>
<P>
Data can also be attached to any LON-CAPA tag.  This is especially important for files.  This is shown by these three examples:
<BR>&lt;METAGROUP&gt;
<BR>&lt;LONCAPA TYPE=LOCATION DIST="redhat6.2" SOURCE="loncom/modules/TexConvert/tthperl/lontex.pm" TARGET="home/httpd/lib/perl/Apache/lontex.pm" CATEGORY="handler"&gt;

<BR>&lt;/TABLE&gt;
<BR>&lt;/NOTE&gt;
<BR>&lt;/METAGROUP&gt;
</P>
<P>
The METAGROUP tags for files are anticipatively limited to: NOTE, BUILD, DEPENDENCIES and DESCRIPTION.
</P>
<P>
To allow for viewing the tag information in a tabular HTML format, the make process generates 
<A HREF="latestinstallconfiguration.html">doc/loncapafiles/latestinstallconfiguration.html</A> which
has the latest HTML presentation of the current LONCAPA tag configuration settings</A>.  Alternatively,
you can just view the internal tags of this HTML file.
</P>

<A NAME="sect2"><H3>2. Software Package Information</H3>

This section contains the actual LONCAPA tag information.  These tags are probably not viewable with your
browser and can only be seen be examining the HTML source.

Summary     : Basic system files for running a LON-CAPA server.
Description :
This package facilitates a base installation of LON-CAPA files in their directories.
The files in this package are only those directly associated with the network communication
layer established through direct server-to-server communications (via lond and lonc); plus
those which configure (but otherwise not constitute) external software packages like Apache
and Athena-Kerberos.  For more on the LON-CAPA project, visit http://www.lon-capa.org/.
