Mac Font Suitcases

Here's a problem that needs solving. All you Mac font experts, can you help with this? Jeremy writes "I am working with updating and revamping an old font archive for Mac. When bringing fonts into ATM, I notice that it won't display fonts unless the folder has a suitcase in it. And if there are PostScript fonts missing from the folder, then the suitcase is reported as missing its outline fonts from ATM." Read all the details and Discuss It in the About Type & Fonts forum.
