# This is a script shell for deploying a meshlab-portable folder and create an AppImage.
# Requires a properly built MeshLab (see 1_build.sh).
#
# Without given arguments, the folder that will be deployed is meshlab/install, which
# should be the path where MeshLab has been installed (default output of 1_build.sh).
# The AppImage will be placed in the directory where the script is run.
#
# You can give as argument the path where you installed MeshLab.
