Introduction

Home Library FTPClient is a Java library providing a simple interface to Home Library WebApp.

This library has following features:

• Current Directory: returns the pathname of the current working directory.

• Remove files and folders: to remove a file or a directory (including subdirectories).
• Test: a simple test to check the correct behavior of the features above.

The following sections will discuss each of these commands in turn, and discuss how to use them with Home Library FTPClient.

Configuration File

Home Library CLI is equipped with a simple configuration file to set the parameters and initial settings.

The fields are:

• URL_REPOSITORY: the URL of Home Library WebApp.
• USERNAME: username to connect to Home Library WebApp.
