+/* NAME
+/*	translit 3
+/* SUMMARY
+/*	transliterate characters
+/* SYNOPSIS
+/*	#include <stringops.h>
+/*
+/*	char	*translit(buf, original, replacement)
+/*	char	*buf;
+/*	char	*original;
+/*	char	*replacement;
+/* DESCRIPTION
+/*	translit() takes a null-terminated string, and replaces characters
+/*	given in its \fIoriginal\fR argument by the corresponding characters
+/*	in the \fIreplacement\fR string. The result value is the \fIbuf\fR
+/*	argument.
+/* BUGS
+/*	Cannot replace null characters.
