Common options:
-q Quiet operation
-p Path to buildroot
Creating build roots (buildlab -C):
-m APK repository mirror
-v APK distribution version
-a APK repository architecture
-k Enable APK caching
Updating build roots (buildlab -u):
No special options.
Building packages (buildlab -b):
-b APKBUILD file
Examples:
sudo ./buildlab -C -p /home/nenolod/buildroot -m dl-3.alpinelinux.org -v edge -a x86_64
sudo ./buildlab -b /home/nenolod/aports/main/gnome-panel/APKBUILD -p /home/nenolod/buildroot
