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).
