-Usage: nd-autoinstall <package> <command> [<command_options>]
+Usage: nd-autoinstall [options] COMMAND [command_options]
+
+Runs the COMMAND if it is available, otherwise installs PACKAGE first,
+and then runs the command. If an environment file is specified, it
+gets sourced first (PACKAGE gets installed if environment file is not
+available).
+
+Options:
+
+ -p, --package=PACKAGE
+ Name of the package to be installed if named differently than
+ COMMAND.
+
+ -e, --environment-file=FILE
+ File to be sourced before invocation of the COMMAND. If not found,
+ PACKAGE gets installed first.
+
+ -f, --force
+ Skip all checks and install package(s) provided via --package.
+
+ -F, --file=FILE
+ If specified file is not present, install the PACKAGE and run
+ the COMMAND.
+
+ -v, --verbose
+ Enable additional progress messages.
+
+ -t, --title
+ Optinal title of the installation dialog.
-Runs the <command> if it is available, otherwise installs <package>
-first, and then runs the command.
+ -h, --help
+ Print short description, usage summary and option list.
+
+ --version
+ Print version information and exit.
Exit status:
- if <command> is available (or got sucesfully installed)
- - exit status of the <command>
+
+ exit status of the COMMAND -
+ if COMMAND is available (or got sucesfully installed)
2 - incorrect invocation of nd-autoinstall
- 3 - <package> installation failure
+ 3 - PACKAGE installation failure
