+/* 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.
