+/* 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
