Input Text File Format

Blank lines are ignored. Lines that begin with a # or ; are assumed to be comments and are ignored.

Each nonblank, noncomment line consists of one or more tokens. A token can be:

• An = (equal) sign.

• A string of characters enclosed by either double quotes, single quotes, or square brackets.

• A series of contiguous nonblank characters.

If a non-string token that begins with a # or a ; is encountered on a line, it and the remaining tokens are assumed to be comments and are ignored.
