# Slackware build script for fdclone

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

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

# This build script owes a debt to the Debian fdclone build
# script. Unlike the Debian build though, I install the binary & man
# pages as "fdclone", not "fd", because SBo already has an "fd". I
# also don't see the point of the stub fdsh man page.

# 20210826 bkw: BUILD=2
# - include missing ToAdmin doc file
# - convert Japanese docs to UTF-8, since nothing on Slackware autodetects
#   ISO-2002-JP (now you can read them with e.g. less).
# - hardcode built-in paths to less and vim (simpler code, and safer too)
