### Conventions and other comments:
|
||||
#
|
||||
# EXIT CODES FOR SCHEME HANDLERS
|
||||
# 0 is for everything went fine
|
||||
# 64 is for "not supported/the problem won't be solved by polling". This is for things like: unmet dependencies, not supported at all, etc
|
||||
# everything else means just "error". Use 1, please. So other codes can be used if needed
