FWEB_HDR_INCLUDES — Colon-delimited list of directories for the C preprocessor (in the form of gcc) to search for ‘#include’ header files. This is used in conjunction with the ‘-H’ option; see -H_. (One can append to this list by means of the ‘-I’ option, provided that option comes after the ‘-H’; see -I_.)

FWEB_INCLUDES — Colon-delimited list of directories to search for ‘@i’ include files. (One can append to this list by means of the ‘-I’ option, provided that option comes before any use of ‘-H’; see -I_.)

FWEB_INI — Name of the initialization file. If not defined, either .fweb or fweb.ini is chosen, depending on the machine. The initialization file always resides in $HOME.

FWEB_STYLE_DIR — Directory in which the style file resides. If not defined, the current directory is used.
