By default, anything following a `#' will be treated as a
comment and ignored. This holds for data files as well as for command
script files loaded with the load command. This default can be
changed with the set comment command. Sometimes a comment
character needs to be taken literally in a script file. The comment
character will be accepted as data if it follows the `\
' escape
operator, i.e. `\
#', or, in the fitting mode only, whenever the
comment character is somewhere inside quotes or parentheses. The
comment character is always accepted literally when typed on the
interactive command line.
