mtools: general syntax

 
 3.2.1 General configuration file syntax
 ---------------------------------------
 
 The configuration files is made up of sections. Each section starts
 with a keyword identifying the section followed by a colon.  Then
 follow variable assignments and flags. Variable assignments take the
 following form:
      name=value
    Flags are lone keywords without an equal sign and value following
 them.  A section either ends at the end of the file or where the next
 section begins.
 
    Lines starting with a hash (`#') are comments. Newline characters
 are equivalent to whitespace (except where ending a comment). The
 configuration file is case insensitive, except for item enclosed in
 quotes (such as filenames).
