For the user's convenience, fwebmac.sty defines a variety of
macros such as \FWEB, \Fortran, etc. Refer to
fwebmac.web for a complete list.
FWEAVE usurps various common single-character macros such as \. for
its own purposes. So the user can still access their original
definitions, those are \let equal to alternative commands
such as \period. For example, commands such as the following are
executed in fwebmac.sty:
\let\amp\&
\let\at\@@
\let\bslash\\
\let\caret\^
\let\dollar\$
\let\dstar\*
\let\equals\=
\let\leftbrace\{
\let\period\.
\let\rightbrace\}
\let\vertbar|
\let\PM\#
\let\PC\%
(Some of the more inscrutable synonyms are for historical reasons.)
