+LIBSVM is an integrated machine learning software for Support Vector
+Machines (SVM).
+This library solves C-SVM classification, nu-SVM classification,
+one-class-SVM, epsilon-SVM regression, and nu-SVM regression. It also
+provides an automatic model selection tool for C-SVM classification.
+
+The script build and install by default also Python bindings to LIBSVM.
+if you are not interested you can disable this option launching the
+slackbuild script as following:
+
+   PYTHON=no ./libsvm.SlackBuild
+
+Dependency python3-scipy is not required if you disable this option.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
