nit q: is this the right way to wrap the string?

[oshima, 2013/08/29 23:30:03]

or it can be

   echo \
"Couldn't find $program. ...."

Let me know which way you prefer.

[msw, 2013/08/29 23:44:09]

How about no wrapping by removing "run setup.exe and" (what setup.exe?).
Or no wrapping by removing 'the' and 'package', like:
      echo "Couldn't find $program. Please run setup.exe and install $package."
Otherwise, I guess I like the '\' wrapping like line 435, but it's just a nit...

     else
       read -p "Couldn't find $program. Do you want to install? (y/n)"
