+lua-readline (lua interface to the readline and history libraries)
+
+This Lua module offers a simple calling interface to the GNU Readline
+and History libraries.
+
+Optional dependencies:
+
+- lua-posix: if this is installed, lua-readline can use it at runtime
+  to determine the user's home directory, if HOME is not set in the
+  environment.
+
+- lua51: if this is installed when the package is built, lua-readline
+  will include a module for Lua 5.1.

+# Written by B. Watson (urchlay@slackware.uk)
+
+# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
+
+# Based on the Arch PKGBUILD:
+# https://aur.archlinux.org/packages/lua-readline
+
+# There used to be a lua-readline on SBo, maintained by abooksigun,
+# based on a different (older, v2.9) source. It was removed in April
+# 2024 because "upstream no longer exists". This isn't quite true:
+# upstream moved the lua-readline site & repo to gitlab. abooksigun
+# says (via email) that he doesn't have the time to maintain this new
+# build, so I will, since I'm up to my eyebrows in lua stuff already.
+
+# This could serve as somewhat of a template for building lua modules
+# from ".rock" files (which are just zip files), though the actual
+# compile command(s) will be different. There's no Makefile or similar
+# inside a .rock. The .rockspec file does give you a hint, but doesn't
+# contain actual compile commands.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
