Node:Preprocessor, Next:Require Statement, Previous:Syntax, Up:Input Language
The preprocessor statements are a GNU extension to the Sieve language.
The syntax for a preprocessor statement is similar to that used in
C programming language, i.e.: a pound character (#)
followed by a preprocessor directive and its arguments. Any amount of
whitespace can be inserted between the # and the directive.
Currently implemented directives are include and searchpath.
