Was supposed to be a linux distribution, now just a collection of build scripts for packages on top of (ideally) any distribution.
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.

-h/? Show this message
-b Set build directory [WARNING: Will be deleted before build]
-s Set source directory
-i Set install directory
-r Set root directory
-p Set prefix directory
-I Nuke install directory before build [WARNING: You will not be prompted]
-d Only download package files
-v Only build vcs package if any updates have been made to it
-o Set package options (comma-separated)
Tips:$([ "$(basename "$0")" = "astronaut" ] && printf "\n- Use \`head -n 55 $0 > astronaut.conf.example\` to generate a default configuration file.")
- Keep in mind that when specifying options on the command line in a string, the first always takes priority.
For example, in \"opt,someotheropt,!opt\", opt is enabled, due to it being the first occurrence.
- If you have set \$dir_satellites in the config, you can omit the .sat suffix.
