With this in my LaTeX file:
\LaunchBinary{lkfs-structure.org}{Open the file Org mode file.}
I get a red boxed link in the pdf output.
When I click on it, Adobe Reader complains:
Could not find an application to open the file ' '.
I can't understand the code for LaunchBinary, but noticed "DOS" and
wondered if the code is somehow dependent on the operating system.
I'm using a Mac.
All the best,
Tom
