installation instructions mention libreadline, libncurses, curl as prerequisites. Why?

jfs.world

as per subject, http://openresty.org/en/installation.html lists among
the list of prerequisites libreadline, libncurses, and curl. Why are
these needed?

I've actually managed to compile and install just fine without these,
so I'm just wondering if these are really needed, and if so, what for.
It's not like openresty provides some sort of text interface, so I
dont see the need for libreadline or libncurses... And I also dont see
how curl is a prerequisite.

thanks,

libreadline and libncurses were needed for the standard Lua 5.1
interpreter. Because we're using LuaJIT by default and will pretty
soon drop the support for the standard Lua interpreter altogether, I
think we can remove these 2 dependencies just fine.

For the "curl" dependency, it is used by the opm command line utility
shipped with OpenResty.

I see. Thank you, Yichun! Appreciate it.
