/* 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.
