# Verify the working copy absolute path using the command path. It is

# not possible to consider relative paths here because we are using a

# symbolic link to create the connection between the centos-art.sh

# script and the centos-art command. The link location is stored

# inside ~/bin directory which is outside the repository directory

# structure. So we cannot use the command path as reference to define

# the repository working directory each time we run the command.

# Instead, in order to get the correct working directory path, it is

# required to finish the script execution when the absolute path

# points to the ~/bin directory and print an error message explaining

# the issue. This message cannot be translated to other languages

# because the TEXTDOMAINDIR variable hasn't been defined yet (it

# requires the working copy directory path to be defined first).
