When the `-e' option is in effect, FWEB attempts to be helpful in figuring out what file name you intend. For any input file name that has no extension (no embedded period), FWEB completes the name by adding the extension contained in the style-file parameter listed in the following table:

Type of file Style-file entry Default

WEB file ext.web .web Change file ext.ch .ch Include file ext.hweb .hweb Change file for include file ext.hch .hch

More than one extension may be specified, as a space-delimited list---e.g., "web wb"; the first one that matches is used.
