"        History: 0.1.0 - working, but it will run the script everytime to check
"                 syntax. Should use osacompile but strangely it does not give
"                 errors.
"
"                 0.2.0 - switch to osacompile, it gives less errors compared
"                 with osascript.
"
"                 0.2.1 - remove g:syntastic_applescript_tempfile. use
"                 tempname() instead.
