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, Maple, Mathematica and Matlab. 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 >8GB 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. NOTE: Future SAGE (7.3+) requires some changes in Slackware's core packages: - readline must be linked to ncurses Get readline's SlackBuild script, change this line make $NUMJOBS static shared || make static shared || exit 1 into make $NUMJOBS static shared SHLIB_LIBS=-lncurses || make static shared SHLIB_LIBS=-lncurses || exit 1 and rebuilt readline. - Python rebuilt against UCS-4 (enabled by default in next Slackware)
