.SH DESCRIPTION
The
Don't ask why it's done this way. There are raisins, but they're mostly
hysterical.
.PP
+The function
+.B pquis
+is passed a file pointer
+.I fp
+and a string
+.IR p :
+it writes the string to the file, replacing every lone occurrence of the
+character
+.RB ` $ '
+by the program name. Pairs
+.RB (` $$ ')
+are written as single dollar signs. The return value is zero if
+everything went OK, or the constant
+.B EOF
+if there was an error.
+.PP
The program name is used in the messages produced by the
.BR die (3)
and
