# Build needs: perl-html-parser
# Needs:       
# Changelog:   
# 3.7-1:       25/oct/2017 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 3.9-1:       20/sep/2019 by Eric Hameleers <alien@slackware.com>
#              * Update.
# 
# Run 'sh netsurf.SlackBuild' to build a Slackware package.
# The package (.t?z) and .txt file as well as build logs are created in /tmp .
# Install the package using 'installpkg' or 'upgradepkg --install-new'.
