+NAME
+	getcwd -- get absolute pathname for current working directory
+
+SYNOPSIS
+	char *getcwd (char pathname[len], len)
+
+DESCRIPTION
+	Copy the absolute pathname for the current working directory into
+	the supplied buffer and return a pointer to the buffer.  If the 
+	current directory's path doesn't fit in LEN characters, the result
+	is NULL and errno is set.
+
+BUGS
+	Emulated via the getwd() call, which is reasonable for most
+	systems that do not have getcwd().
