A.3 Configuration files
Most configuration files have a common form:
- Each line forms a separate command or directive. This means that lines
cannot be broken up, unless they are spliced together with a trailing
backslash, as described below.
- Before anything else is done, trailing white space is removed.
- When a line ends in a backslash (‘\’), the backslash is removed,
and the next line is read and appended to the current line.
- White space preceding the backslash is retained.
- This rule continues to be applied until the line read does not end in a
- It is an error if the last line in the file ends in a backslash.
- Comments are introduced by an octothorpe (‘#’), and continue until the
end of the line.
- Blank lines, and lines that contain only white space, are ignored.
