+This is a script to package Octave-Forge, the main source for
+out-of-mainline Octave packages.
+
+The Octave-Forge packages are grouped into four categories (main,
+extra, language and nonfree). By default the script packages all of
+them, but you can specify a different behavior with the REPOS
+variable. For example,
+  REPOS=main,extra ./octave-forge.SlackBuild
+will build only the "main" and "extra" repositories.
+Parallel compilation (JOBS=...) is not supported.
+
+If you want to build a newer version of Octave-Forge, you need to
+regenerate the Octave script that performs the build itself. To do
+this, run generate-installscript.sh after updating the usual variables
+near the beginning.
+
+This script requires Octave, available on SlackBuilds.org.
+Some packages also have dependencies on external components, not
+available on stock Slackware or SlackBuilds.org. These components
+(and, more generally, packages failing compilation) are automatically
+excluded from the package.
+
+Note: on package removal, you should run as root:
+  mkdir -p /usr/share/octave/packages && \
+  octave --silent --eval "pkg rebuild"

+# 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
