META-INF/MANIFEST.MF - JAR Manifest File
This section describes the JAR manifest file, META-INF/MANIFEST.MF, which contains information about the JAR file and its contents.
"manifest" in a JAR file is a file named as META-INF/MANIFEST.MF. It contains attributes about the JAR file and its contents.
Attributes in "manifest" are recorded as a list of name-value pairs in the form of "name: value\n". The list is divided into a main section for package-level attributes and multiple sub sections for entry-level attributes. Note that each attribute must be ended with a new line character.
The main section may contain only the package level attributes like:
Sub sections are optional. They are used to provide entry-level attributes with one section per entry. A sub sections must be preceded with a blank line and started with a "Name" attribute to associate this section with a content entry in the JAR file.
