			NAME: ${Green}$AMCLIUPPER\033[0m		VERSION: ${Green}$AMVERSION\033[0m

			SYNOPSIS:	${LightBlue}$AMCLI {OPTION}\033[0m
					${LightBlue}$AMCLI {OPTION} {PROGRAM}\033[0m

			DESCRIPTION: A command line utility to install and manage AppImages and other portable programs for GNU/Linux thanks to its AUR-inspired database.

			OPTIONS:
			 
			${Gold}about, -a\033[0m

					${LightBlue}$AMCLI -a {PROGRAM}\033[0m

			Description: Shows more info about one or more apps.

			${Gold}apikey\033[0m

					${LightBlue}$AMCLI apikey {Github Token}
					${LightBlue}$AMCLI apikey delete\033[0m

			Description: Accede to github APIs using your personal access tokens. The file named \"ghapikey.txt\" will be saved in $AMDATADIR. Use \"del\" to remove it.

			${Gold}backup, -b\033[0m

					${LightBlue}$AMCLI -b {PROGRAM}\033[0m

			Description: Create a snapshot of the current version of an installed program.

			${Gold}clean, -c\033[0m

					${LightBlue}$AMCLI -c\033[0m

			Description: Removes all the unnecessary files and folders.

			${Gold}config, -C, --config\033[0m

					${LightBlue}$AMCLI -C {PROGRAM}\033[0m

			Description: Set a dedicated \$XDD_CONFIG_HOME for one or more AppImages.

			${Gold}downgrade, --rollback\033[0m

					${LightBlue}$AMCLI --rollback {PROGRAM}\033[0m

			Description: Download an older or specific app version.

			${Gold}download, -d\033[0m

					${LightBlue}$AMCLI -d {PROGRAM}
					${LightBlue}$AMCLI -d --convert {PROGRAM}\033[0m

			Description: Download one or more installation scripts to your desktop or convert them to local installers for \"AppMan\".

			${Gold}extra, -e\033[0m

					${LightBlue}$AMCLI -e user/project {APPNAME}
					${LightBlue}$AMCLI -e user/project {APPNAME} {KEYWORD}\033[0m

			Description: Install AppImages from github.com, outside the database. This allows you to install, update and manage them all like the others. Where \"user/project\" can be the whole URL to the github repository, give a name to the program so that it can be used from the command line. Optionally, add an \"univoque\" keyword if multiple AppImages are listed.

			${Gold}files, -f\033[0m

					${LightBlue}$AMCLI -f
					${LightBlue}$AMCLI -f --byname
					${LightBlue}$AMCLI -f --less\033[0m

			Description: Shows the list of all installed programs, with sizes. By default apps are sorted by size, use \"--byname\" to sort by name. With the option \"--less\" it shows only the number of installed apps.

			${Gold}help, -h\033[0m

					${LightBlue}$AMCLI -h\033[0m

			Description: Prints this message.

			${Gold}home, -H, --home\033[0m

					${LightBlue}$AMCLI -H {PROGRAM}\033[0m

			Description: Set a dedicated \$HOME directory for one or more AppImages.

			${Gold}icons, --icons\033[0m

					${LightBlue}$AMCLI --icons {PROGRAM}
					${LightBlue}$AMCLI --icons --all\033[0m

			Description: Allow installed apps to use system icon themes. You can specify the name of the apps to change or use the \"--all\" flag to change all of them at once. This will remove the icon path from the .desktop file and add the symbolic link of all available icons in the $DATADIR/icons/hicolor/scalable/apps directory. The \"--icons\" option can be used as \"flag\" in the \"-i\" and \"-ia\" options.

			${Gold}install, -i\033[0m

					${LightBlue}$AMCLI -i {PROGRAM}
					${LightBlue}$AMCLI -i --debug {PROGRAM}
					${LightBlue}$AMCLI -i --force-latest {PROGRAM}
					${LightBlue}$AMCLI -i --icons {PROGRAM}\033[0m

			Description: Install one or more programs or libraries from the list. With the \"--debug\" option you can see log messages to debug the script. For more details on \"--force-latest\", see the dedicated option, below. Use the \"--icons\" flag to allow the program to use icon themes. It can also be extended with additional flags (see \"--toolpack\").

			${Gold}install-appimage, -ia\033[0m

					${LightBlue}$AMCLI -ia {PROGRAM}
					${LightBlue}$AMCLI -ia --debug {PROGRAM}
					${LightBlue}$AMCLI -ia --force-latest {PROGRAM}
					${LightBlue}$AMCLI -ia --icons {PROGRAM}\033[0m

			Description: Same as \"install\" (see above) but for AppImages only.

			${Gold}lock\033[0m

					${LightBlue}$AMCLI lock {PROGRAM}\033[0m

			Description: Prevent an application being updated, if it has an\"AM-updater\" script.

			${Gold}list, -l\033[0m

					${LightBlue}$AMCLI -l
					${LightBlue}$AMCLI -l --all
					${LightBlue}$AMCLI -l --appimages
					${LightBlue}$AMCLI -l --toolpack {KEYWORD}\033[0m

			Description: Shows the list of all the apps available, or just the AppImages. It can also be extended with additional flags, the \"--all\" flag allows you to consult the set of all supported databases (see \"--toolpack\").

			${Gold}newrepo, neodb\033[0m

					${LightBlue}$AMCLI newrepo add {URL}\\{PATH}
					${LightBlue}$AMCLI newrepo select
					${LightBlue}$AMCLI newrepo on\\off
					${LightBlue}$AMCLI newrepo purge
					${LightBlue}$AMCLI newrepo info\033[0m

			Description: Set a new default repo, use \"add\" to append the path to a local directory or an online URL, then use \"select\" to use it by default, a message will warn you about the usage of this repo instead of the default one. Use \"on\"/\"off\" to enable/disable it. Use \"purge\" to remove all 3rd party repos. Use \"info\" to see the source from where installation scripts and lists are taken.

			${Gold}nolibfuse\033[0m

					${LightBlue}$AMCLI nolibfuse {PROGRAM}\033[0m

			Description: Convert old AppImages and get rid of \"libfuse2\" dependence.

			${Gold}overwrite, -o\033[0m

					${LightBlue}$AMCLI -o {PROGRAM}\033[0m

			Description: Overwrite apps with snapshots saved previously (see \"-b\").

			${Gold}query, -q\033[0m

					${LightBlue}$AMCLI -q {KEYWORD}
					${LightBlue}$AMCLI -q --all {KEYWORD}
					${LightBlue}$AMCLI -q --appimages {KEYWORD}
					${LightBlue}$AMCLI -q --pkg {PROGRAM1} {PROGRAM2}
					${LightBlue}$AMCLI -q --toolpack {KEYWORD}\033[0m

			Description: Search for keywords in the list of available applications, add the \"--appimages\" option to list only the AppImages or add \"--pkg\" to list multiple programs at once. It can also be extended with additional flags, the \"--all\" flag allows you to consult the set of all supported databases (see \"--toolpack\").

			${Gold}remove, -r\033[0m
