11///
12/// Entries are the main building blocks of Fluent.
13///
14/// They define translations and contextual and semantic information about the
15/// translations. During the AST construction, adjacent comment lines of the same
16/// comment type (defined by the number of #) are joined together. Single-# comments
17/// directly preceding [Message](crate::ast::Message)s and [Term](crate::ast::Term)s
18/// are attached to the [Message](crate::ast::Message) or [Term](crate::ast::Term)
19/// and are not standalone Entries.
