+/* NAME
+/*	argv_split 3
+/* SUMMARY
+/*	string array utilities
+/* SYNOPSIS
+/*	#include <argv.h>
+/*
+/*	ARGV	*argv_split(string, delim)
+/*	const char *string;
+/*	const char *delim;
+/*
+/*	ARGV	*argv_split_count(string, delim, count)
+/*	const char *string;
+/*	const char *delim;
+/*	ssize_t	count;
+/*
+/*	ARGV	*argv_split_append(argv, string, delim)
+/*	ARGV	*argv;
+/*	const char *string;
+/*	const char *delim;
+/* DESCRIPTION
+/*	argv_split() breaks up \fIstring\fR into tokens according
+/*	to the delimiters specified in \fIdelim\fR. The result is
+/*	a null-terminated string array.
+/*
+/*	argv_split_count() is like argv_split() 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_append() performs the same operation as argv_split(),
+/*	but appends the result to an existing string array.
+/* SEE ALSO
+/*	mystrtok(), safe string splitter.
+/* DIAGNOSTICS
+/*	Fatal errors: memory allocation problem.
