inn2 batch creating cyclic buffers

##
## Rules for where INN should store incoming articles.
##
## This file is used to determine which storage method articles are sent
## to be stored and which storage class they are stored as. Each
## method is described as follows:
##
## method <methodname> {
## newsgroups: <wildmat>
## class: <storage class #>
## size: <minsize>[,<maxsize>]
## expires: <mintime>[,<maxtime>]
## options: <options>
## exactmatch: <bool>
## }
##
## See the storage.conf man page for more information.
##
## Only newsgroups, class, and (for CNFS, to specify the metacycbuff)
## options are required; the other keys are optional. If any CNFS
## methods are configured, you will also need to set up cycbuff.conf.

## By default, store everything in tradspool.

#method tradspool {
# newsgroups: *
# class: 0
#}

## Here are some samples for a CNFS configuration. This assumes that you
## have two metacycbuffs configured, one for text newsgroups and one for
## binaries. Cancel messages, which tend to be very high-volume, are
## stored in the binary metacycbuff as well. This assumes storeonxref is
## set to true in inn.conf.

## Pick off the binary newsgroups first.

#method cnfs {
# newsgroups: *.bina*,control.cancel
# class: 1
# options: BINARY
#}

## Put the remaining (text) groups in the other cycbuff.

#method cnfs {
# newsgroups: *
# class: 2
# options: TEXT
#}

method cnfs {
newsgroups: *
class: 201
options: LOW
size: 0,32000
}

method cnfs {
newsgroups: *
class: 202
options: MID
size: 32000,128000
}

method cnfs {
newsgroups: *
class: 203
options: BIG
size: 128000,256000
}

method cnfs {
newsgroups: *
class: 204
options: HUG
size: 256000,1000000
}

method cnfs {
newsgroups: *
class: 205
options: MEG
size: 1000000,15000000
}

# trash

method trash {
newsgroups: *
class: 255
}
