# The file /etc/apk/repositories contains a list of the apk repositories. By
# default contains this file a list of the stable repositories pointing to the
# alpine version.

# Some perl packages are not part of the stable repositories. For this reason
# are the repositories switched to edge to access directly the latest versions
# of this apk packages.
#
# Using stable and edge at the same time is not allowed. For more information,
# take a look into the documentation of the edge repository.
