$platform$-deploy.[sh/ps1]: a script that deploys MeshLab, making sure that the folder will be a self-contained MeshLab, without Qt library dependencies. Requires a properly built MeshLab in the directory passed as an argument, or in the distrib folder if arguments were not provided.
$platform$-$installer$.[sh/ps1]: a script that computes a self-contained package/installer of MeshLab. Requires a properly deployed MeshLab in the directory passed as an argument, or in the distrib folder if arguments were not provided. The result will be saved in the same directory.
$platform$-make_it.[sh/ps1]: a script that computes all the three previous scripts: starting from the source code, it will produce a self-contained package/installer of MeshLab.
