+- [cl-ftp](https://github.com/pinterface/cl-ftp). This is a typical Lisp library that looks abandoned, but just works©.
+
+It is available under the `ftp` package name. Here's a quick snippet:
+
+```lisp
+(ftp:with-ftp-connection (conn :hostname (get-hostname)
+                               :username (get-ftp-username)

+      (ftp:store-file conn in-filename out-filanem))
+```
