# Slackware build script for surf

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20230115 bkw: BUILD=2, strip library.
# 20211020 bkw:
# - updated for v2.1.
# - rework patches again, can't build old versions no more.
# - embiggen the default window size to 1280x1024.

# 20170625 bkw:
# - updated for v2.0 (webkit2gtk now required).
# - re-work searchengines.diff and homepage.diff for v2.0.
# - remove "sw" search from searchengines.diff, since packages.slackware.eu
#   no longer exists. Before you ask, no, I can't replace it with the official
#   search at packages.slackware.com, because searchengines.diff only does
#   HTTP GET requests. Find me a working Slackware package search that doesn't
#   require a POST request, and I'll add it to searchengines.diff.

# 20170121 bkw:
# - updated for v0.7.
# - remove patches/startfullscreen.diff as it's integrated into 0.7
# - update homepage.diff and searchengines.diff for 0.7
