308 * extension isn't sufficient to determine the appropriate file type,

315 * 2) packaging/macosx/Info.plist.in (for OS X)
316 * 3) packaging/nsis/AdditionalTasksPage.ini and packaging/nsis/common.nsh
319 * If your file format has an expected extension (e.g., ".pcap") then you
320 * should probably also add it to file_type_extensions_base[] (in this file).
