# Simple deferred project authorisation
#
# This implements simple project authorisation
# by whether the user performing the access is listed in the per-repository
# configuration variables:
#
# 1.  project.readers if they are performing a read operation (clone, fetch),
# 2.  project.writers if they are performing a write operation (push).
#
# This is intended as a sane default for sites with small numbers of users
# and repositories, where it's feasible to authorise each repository by hand.
#
# For larger numbers of repositories and users,
# delegating permission to manage groups to users,
# and letting users grant access to repositories by group membership is better.
#
# It can be enabled before main.lace (inside gitano-admin rules/project.lace)
# to require all repositories support config variable based authorisation,
# or after main.lace (inside gitano-admin rules/core.lace)
# if projects may insist on interpreting the variables differently.
