+Sage is a free open-source mathematics software system licensed under 
+the GPL. It combines the power of many existing open-source packages 
+into a common Python-based interface. 
+Mission: Creating a viable free open source alternative to Magma, 
+
+Sage can be used in several ways: through an interactive command line, 
+by writing stand-alone scripts, through the graphical notebook 
+interface in a browser, or through the KDE Cantor application (part
+of a full Slackware installation).
+
+Building sage requires >5GB of disk space, so you may need to
+redefine $TMP and/or $OUTPUT.
+
+See README.BUILDOPTS for additional (important) information about
+build options and such.

+Sage uses specific versions of a number of software components (i.e. 
+R, gap, gp, ipython, maxima, mwrank, hg, python, singular, etc.).  Each 
+of thes components will be compiled during the build process and 
+installed to a local tree (/opt/sage).  The sage directory will be 
+placed in /opt, however it should be portable enough to be moved to any
+location.
+
+SlackBuild Options:
+
+SAGEROOT=/install/path [Default:/opt/sage]
+By default, sage will be installed to /opt/sage.  However, the sage
+folder is portable and can be installed to any location of your
+choosing.  The final destination for SAGE_ROOT can be specified 
+by passing a value for SAGEROOT to the slackbuild.  The final install
+will be >2GB, so you may need to point SAGEROOT to a different
+partition if your /opt partition is not large enough.  The sage tree
+can also be moved after installation, however you will need to update
+the sage.* scripts in /etc/profile.d to point to the new SAGE_ROOT.  
+Example: to install sage to your home directory do the following
+SAGEROOT=/home/user/opt/sage ./sage.SlackBuild
+
+TEST={yes|no} [Default:no]
+All examples in the documentation (over 93,000 lines of input) can be
+tested after Sage has been built with the following (Note: it is not 
+uncommon for this to produce 2 or 3 errors)
+TEST=yes ./sage.SlackBuild
+
+INSTALLSCRIPTS={yes|no} [Default:no]
+Sage's local versions of R, gap, gp, ipython, maxima, mwrank, hg, and 
+singular can be used independently of Sage by placing scripts for each
+in the PATH. This can be enabled with the following (Note: the scripts
+will be installed to the location SAGEROOT/bin)
+INSTALLSCRIPTS=yes ./sage.SlackBuild
+
+PDFDOC={yes|no} [Default:no]
+By default, only the html version of the documentation will be built.
+The pdf version can be built with the following (Note: this requires 
+LaTeX to be installed):
+PDFDOC=yes ./sage.Slackbuild
+
+OPTIONALSPKG={package1|"package1 package2 ..."|no} [Default:no]
+There are a number of optional .spkg files (packages) that can be
+be installed after sage has been built.  These packages are downloaded
+from a sage server before they are installed, therefore you will need a 
+network connection for this to work.  A list of the available optional 
+packages and a description of each can be found at 
+http://www.sagemath.org/packages/optional
+These packages can be installed with the following (Note: it is not 
+necessary to give the full version number of the package you are
+installing, simply giving the base name is sufficient):
+OPTIONALSPKG="package1 package2 package3 ..." ./sage.SlackBuild
+
+The upstream developers "highly recommend" the database_gap package, 
+which would be installed with
+OPTIONALSPKG="database_gap" ./sage.SlackBuild
+
+To install multiple packages, i.e. the database_gap package and the 
+sage-mod package do the following:
+OPTIONALSPKG="database_gap sage-mod" ./sage.SlackBuild
