Hi Albert,

Thanks for the swift response. That did the trick. I am amble to run the 
include-file filter now.

The next thing is that I run into this issue:
:~/workspace/lua-filters/include-files$ ./run-it.sh 
Error running filter include-files.lua:
error loading module 'socket.core' from file 
'/opt/zbstudio/bin/linux/x64/clibs53/socket/core.so':
        *Dynamic loading not supported*
stack traceback:
        [C]: in ?
        [C]: in function 'require'
        /opt/zbstudio/lualibs/socket.lua:12: in main chunk
        [C]: in function 'require'
        /opt/zbstudio/lualibs/mobdebug/mobdebug.lua:102: in main chunk
        [C]: in function 'require'
        include-files.lua:13: in main chunk

I do the following... I set my variables like so:
export ZBS=/opt/zbstudio
export LUA_PATH="./?.lua;$ZBS/lualibs/?/?.lua;$ZBS/lualibs/?.lua"
export LUA_CPATH="$ZBS/bin/linux/x64/?.so;$ZBS/bin/linux/x64/clibs53/?.so"

My architecture is:
$ uname -i
x86_64

pandoc uses LUA5.3

There is some remark in the troubleshooting section about dynamic libraries 
not enabled:
"

   - 
   
   *I get dynamic libraries not enabled error.* You may get the following 
   error when loading socket.core on Linux: *error loading module 
   ‘socket.core’ from file ‘/opt/zstudio/bin/linux/x86/clibs/socket/core.so’: 
   dynamic libraries not enabled; check your Lua installation*. This most 
   likely means that the Lua interpreter you are using was built 
   without LUA_USE_DLOPEN option enabled. You can either enable it or 
   statically link your application with luasocket.
   
"
I am using the lua that comes with the debugger and pandoc. The 
troubleshooting section does not really give a pointer where to go next. 
What could this be?
