LuaRocks help

[Geoff Leyland <geoff_leyland@...>]

Hi,

I just installed luarocks through macports, and it all seems to be  
working fine - much easier than all the build-it-myself that I'd been  
doing before.  I had to add "/opt/local/lib/luarocks/bin" to my path  
to find the scripts I installed, but that's a macports thing.
Now, to use the luarocks installed modules without changing my source,  
I have to go
lua -lluarocks.require script.lua

which is a bit wordy.  Is there a "best practice" for this?  Do people  
set LUA_INIT to "require'luarocks.require'" or "@/whereisit/luarocks/ 
require.lua"?  Or alias lua to 'lua -lluarocks.require'?  Any other  
ideas?  I haven't found this mentioned on the mailing list, but please  
point me that way if it's a faq.
Also, I installed markdown.lua with luarocks.  What now?  I used to go  
"lua markdown.lua file.txt" or even "markdown.lua file.txt", but now  
the best I've managed is
lua /opt/local/lib/luarocks/rocks/markdown/0.32-1/lua/markdown.lua  
file.txt
It's no problem to stick that in a script or alias it if that's the  
right thing to do, but I can't help but think I'm missing something  
really obvious.  Am I?
Cheers, and thanks,
Geoff
