# Slackware build script for doomseeker

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

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

# 20260802 bkw: updated for v1.5.3. original site down, use github.
# 20230111 bkw: updated for v1.3.3.
# 20211102 bkw:
# - updated for v1.3.2.
# - new-style icons.
# - /usr/share/doomseeker => /usr/share/games/doomseeker.

# 20201030 bkw: updated for v1.3.1
# 20200122 bkw: updated for v1.3+20200119_b623ab1. Latest git fixes
# a segfault issue that normally only occurs when starting doomseeker
# without ~/.config/doomseeker/* (so the previous version worked for me,
# but wouldn't for a new user).
# 20191211 bkw: updated for v1.3. qt4 support was dropped, qt5 now required.
# 20181218 bkw: updated for v1.2. Upstream has changed things around,
# so this script won't build 1.1 any longer.
