##  usually only name my Love2D scripts  "main.lua"  so this method works well.
##  other Lua scripts will execute w/ your system Lua instead.

if [ -e main.lua ] ; then  ##  try current dir
  looking_for_lua=false
  love .
  else if [ -e ../main.lua ] ; then  ##  try parent dir
    looking_for_lua=false
    love ../.
    else if [ -e ../../main.lua ] ; then  ##  try grandparent dir
      looking_for_lua=false
      love ../../.
      else if [ -e ../../../main.lua ] ; then  ##  one more for good measure
        looking_for_lua=false
        love ../../../.

##  haven't found a Love2D script, try running it in Lua instead

##  You can nest the "main.lua" search further than 4 deep if you really need to,
##  but this seems to suit my purpose.  I wouldn't want it traversing
##  nonstop up the filesystem hunting for something that doesn't exist.
