What is a(n) MF file?

The MF (Java Manifest Format) is a simple text file used by the Java platform to store configuration information for an application or library. It typically contains version, vendor, and package information about the associated application or library. A Manifest File must be at the root of each Java JAR archive, just after the /META-INF/ directory. It is composed of name-value pairs, one per line.

To ensure that Manifest files can be parsed correctly no matter what format they are in, all entries must be encoded in UTF-8. Also, for compatibility with different computing environments, lines should be terminated with CR+LF (Carriage Return + Line Feed) characters. Each entry is typically between 4 and 72 characters long, and can contain version numbers, URLs, java class names, and other information.
