This allows multiple users of the same system to be able to use the same installed applications, **while the general use of "AM" (installing, updating, consulting lists...) will only be permitted to the system administrator/owner of the /opt/am directory and all the directories managed by "AM", and to the user "root"**.

 Since version 5.1 the installation process have introduced a check to find read-only filesystems (`grep "[[:space:]]ro[[:space:],]" /proc/mounts`), if there are mountpoints like this, your distro may be an immutable one, so an `/usr/local/share/applications` directory will be created and the installation script will be patched to redirect the installation of launchers in that path to solve the issue.

 - "AppMan" (ie the `appman` command) instead does not need root privileges to work, it allows you to choose where to install your applications into your `$HOME` directory. AppMan is also usable as a portable app (i.e. you can download and place it wherever you want) and it is able to update itself, anywhere! At first start it will ask you where to install the apps and it will create the directory for you (the configuration file is in `~/.config/appman`). For example, suppose you want install everything in "Applicazioni" (the italian of "applications"), this is the structure of what an installation scripts installs with "AppMan" instead:
 
       ~/Applicazioni/$PROGRAM/

 Since version 5.1 the installation process have introduced a check to find read-only filesystems (`grep "[[:space:]]ro[[:space:],]" /proc/mounts`), if there are mountpoints like this, your distro may be an immutable one, so an `/usr/local/share/applications` directory will be created and the installation script will be patched to redirect the installation of launchers in that path to solve the issue.

 - "AppMan" (ie the `appman` command) instead does not need root privileges to work, it allows you to choose where to install your applications into your `$HOME` directory. AppMan is also usable as a portable app (i.e. you can download and place it wherever you want) and it is able to update itself, anywhere! At first start it will ask you where to install the apps and it will create the directory for you (the configuration file is in `~/.config/appman`). For example, suppose you want install everything in "Applicazioni" (the italian of "applications"), this is the structure of what an installation scripts installs with "AppMan" instead:
 
       ~/Applicazioni/$PROGRAM/
