+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().
