setting up mailman-to-atom-converter then atom-to-public-inbox

[Luke Kenneth Casson Leighton <lkcl@lkcl.net>]

hi, just as the subject says, i'm currently modifying mailman_rss to
support atom and would like to set it up on libre-soc.org shortly.

firstly: very grateful that public-inbox even exists, it is kinda
important to have really, really simple offline archives of project
mailing lists.

second: i have no idea how to go about setting it up :)

third: sigh, i have two unknowns (three), because i am actually
modifying mailman_rss to support atom, *and* i would prefer not to
overload my server by splitting up the creation of atom feeds into
multiple separate processing sections (by month) *and* i have no idea
if public-inbox can support feeds-of-feeds.

to explain / unpack that: here's how i would envisage the workflow so
as to minimise the server load:

* cron job goes through the monthly mailman archives *by month*
performing a re-creation *only* of the latest month's atom feed
* same cron job adds to a "global" atom file containing "links to the
monthly atom files"
* public-inbox sees that list-of-monthly-atom-files
* public-inbox walks the "tree" of monthly atom files, grabbing each one in turn
* public-inbox loads all messages from all monthly atom files.

is this possible or does public-inbox expect one whopping monster
resource-hogging beast-of-an-atom-file potentially hundreds of
megabytes long?  (the reason i ask all this is because the server i am
running this on only has 1GB of RAM and i'm not going to be upgrading
it as it costs money).

tia,

l.
