+/* NAME
+/*	argv_split_at 3
+/* SUMMARY
+/*	string array utilities
+/* SYNOPSIS
+/*	#include <argv.h>
+/*
+/*	ARGV	*argv_split_at(string, sep)
+/*	const char *string;
+/*	int	sep;
+/*
+/*	ARGV	*argv_split_at_count(string, sep, count)
+/*	const char *string;
+/*	int	sep;
+/*	ssize_t	count;
+/*
+/*	ARGV	*argv_split_at_append(argv, string, sep)
+/*	ARGV	*argv;
+/*	const char *string;
+/*	int	sep;
+/* DESCRIPTION
+/*	argv_split_at() splits \fIstring\fR into fields using a
+/*	single separator specified in \fIsep\fR. The result is a
+/*	null-terminated string array.
+/*
+/*	argv_split_at_count() is like argv_split_at() but stops
+/*	splitting input after at most \fIcount\fR -1 times and
+/*	leaves the remainder, if any, in the last array element.
+/*	It is an error to specify a count < 1.
+/*
+/*	argv_split_at_append() performs the same operation as
+/*	argv_split_at(), but appends the result to an existing
+/*	string array.
+/* SEE ALSO
+/*	split_at(), trivial string splitter.
+/* DIAGNOSTICS
+/*	Fatal errors: memory allocation problem.
+/* LICENSE
