=head1 NAME

project-proper-path - Print the proper path of the project based in the working directory

=head1 SYNOPSIS

project-proper-path

perldoc project-proper-path

=head1 DESCRIPTION

This works as advertised only if the working directory is the base directory of a project.

Prints the proper path (without a trailing slash) of the project that is (or would be) installed
in the working directory.  Fails with an error message if the working directory is detected
to be outside of the command directory or one that is structurally mapped to it.

=head1 EXAMPLES

 ~/work/wayic/cast> project-proper-path

    → wayic/cast

 ~/var/repo/git/wayic.cast.git> project-proper-path

    → wayic/cast

 ~/work/wayic/Waybrec> project-proper-path

    → wayic/Waybrec

 ~/var/repo/git/Waybrec.git> project-proper-path

    → wayic/Waybrec
