- ** READCF -- read configuration file.
- **
- ** This routine reads the configuration file and builds the internal
- ** form.
- **
- ** The file is formatted as a sequence of lines, each taken
- ** atomically. The first character of each line describes how
- ** the line is to be interpreted. The lines are:
- ** Dxval Define macro x to have value val.
- ** Cxword Put word into class x.
- ** Fxfile [fmt] Read file for lines to put into
- ** class x. Use scanf string 'fmt'
- ** or "%s" if not present. Fmt should
- ** only produce one string-valued result.
- ** Hname: value Define header with field-name 'name'
- ** and value as specified; this will be
- ** macro expanded immediately before
- ** use.
- ** Sn Use rewriting set n.
- ** Rlhs rhs Rewrite addresses that match lhs to
- ** be rhs.
- ** Mn arg=val... Define mailer. n is the internal name.
- ** Args specify mailer parameters.
- ** Oxvalue Set option x to value.
- ** Pname=value Set precedence name to value.
- ** Vversioncode[/vendorcode]
- ** Version level/vendor name of
- ** configuration syntax.
- ** Kmapname mapclass arguments....
- ** Define keyed lookup of a given class.
- ** Arguments are class dependent.
- ** Eenvar=value Set the environment value to the given value.
- **
- ** Parameters:
- ** cfname -- configuration file name.
- ** safe -- TRUE if this is the system config file;
- ** FALSE otherwise.
- ** e -- the main envelope.
- **
- ** Returns:
- ** none.
- **
- ** Side Effects:
- ** Builds several internal tables.
