# Slackware build script for filerunner

# Upstream's official RPM release claims to be noarch, but it's a dirty
# lie: it includes libinotify1.4.1.so binaries[*] for various arches. So
# does the source, but we're not trusting binaries that were probably
# built on Red Hat. The source for the prebuilt binaries is included,
# so this script compiles it instead.

# [*] It breaks FHS and Slackware standards by installing arch-dependent
#     files (shared libs) in /usr/share, too. But I'm going to leave it
#     that way.
