+/* NAME
+/*	split_at 3
+/* SUMMARY
+/*	trivial token splitter
+/* SYNOPSIS
+/*	#include <split_at.h>
+/*
+/*	char	*split_at(string, delimiter)
+/*	char	*string;
+/*	int	delimiter
+/*
+/*	char	*split_at_right(string, delimiter)
+/*	char	*string;
+/*	int	delimiter
+/* DESCRIPTION
+/*	split_at() null-terminates the \fIstring\fR at the first
+/*	occurrence of the \fIdelimiter\fR character found, and
+/*	returns a pointer to the remainder.
+/*
+/*	split_at_right() looks for the rightmost delimiter
+/*	occurrence, but is otherwise identical to split_at().
+/* DIAGNOSTICS
+/*	The result is a null pointer when the delimiter character
+/*	was not found.
+/* HISTORY
+/* .ad
+/* .fi
+/*	A split_at() routine appears in the TCP Wrapper software
+/*	by Wietse Venema.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
