The home of 'Abort' is 'error' not 'util' however, a lot of code seems to be confused about that and gives all the credit to 'util' instead of the hardworking 'error'. In a spirit of equity, we break the cycle of injustice and give back to 'error' the respect it deserves. And screw that 'util' poser. For great justice.

'''http authentication with factotum
|
|
|
|
This extension allows the factotum(4) facility on Plan 9 from Bell Labs
|
|
platforms to provide authentication information for HTTP access. Configuration
|
|
entries specified in the auth section as well as authentication information
|
|
provided in the repository URL are fully supported. If no prefix is specified,
|
|
a value of "*" will be assumed.
|
|
|
|
By default, keys are specified as::
|
|
|
|
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
|
|
|
|
If the factotum extension is unable to read the required key, one will be
|
|
requested interactively.
|
|
|
|
A configuration section is available to customize runtime behavior. By
|
|
default, these entries are::
|
|
|
|
[factotum]
|
|
executable = /bin/auth/factotum
|
|
mountpoint = /mnt/factotum
|
|
service = hg
|
|
|
|
The executable entry defines the full path to the factotum binary. The
|
|
mountpoint entry defines the path to the factotum file service. Lastly, the
|
|
service entry controls the service name used when reading keys.
