    HACKING/design: remove 03-modules as superseded.
    
    The src/feature directory documentation now covers this better.

-## Tor's modules ##
-
-### Node-status modules ###
-
-`directory.c`
-: Implements the HTTP-based directory protocol, including sending,
-receiving, and handling most request types.  (*Note*: The client parts
-of this, and the generic-HTTP parts of this, could plausibly be split
-off.)
-
-`microdesc.c`
-: Implements the compact "microdescriptor" format for keeping track of
-what we know about a router.
-
-`networkstatus.c`
-: Code for fetching, storing, and interpreting consensus vote documents.
-
-`nodelist.c`
-: Higher-level view of our knowledge of which Tor servers exist.  Each
-`node_t` corresponds to a router we know about.
-
-`routerlist.c`
-: Code for storing and retrieving router descriptors and extrainfo
-documents.
-
-`routerparse.c`
-: Generic and specific code for parsing all Tor directory information
-types.
-
-`routerset.c`
-: Parses and interprets a specification for a set of routers (by IP
-range, fingerprint, nickname (deprecated), or country).
-
-
-### Client modules ###
-
-`addressmap.c`
-: Handles client-side associations between one address and another.
-These are used to implement client-side DNS caching (NOT RECOMMENDED),
-MapAddress directives, Automapping, and more.
-
-`circpathbias.c`
-: Path bias attack detection for circuits: tracks whether
-connections made through a particular guard have an unusually high failure rate.
-
-`circuitstats.c`
-: Code to track circuit performance statistics in order to adapt our behavior.
-Notably includes an algorithm to track circuit build times.
-
-`dnsserv.c`
-: Implements DNSPort for clients. (Note that in spite of the word
-"server" in this module's name, it is used for Tor clients.  It
-implements a DNS server, not DNS for servers.)
-
-`entrynodes.c`
-: Chooses, monitors, and remembers guard nodes.  Also contains some
-bridge-related code.
-
-`torcert.c`
-: Code to interpret and generate Ed25519-based certificates.
-
-### Server modules ###
-
-`dns.c`
-: Server-side DNS code.  Handles sending and receiving DNS requests on
-exit nodes, and implements the server-side DNS cache.
-
-`dirserv.c`
-: Implements part of directory caches that handles responding to
-client requests.
-
-`ext_orport.c`
-: Implements the extended ORPort protocol for communication between
-server-side pluggable transports and Tor servers.
-
-`hibernate.c`
-: Performs bandwidth accounting, and puts Tor relays into hibernation
-when their bandwidth is exhausted.
-
-`router.c`
-: Management code for running a Tor server. In charge of RSA key
-maintenance, descriptor generation and uploading.
-
-`routerkeys.c`
-: Key handling code for a Tor server. (Currently handles only the
-Ed25519 keys, but the RSA keys could be moved here too.)
-
-
-### Onion service modules ###
-
-`rendcache.c`
-: Stores onion service descriptors.
-
-`rendclient.c`
-: Client-side implementation of the onion service protocol.
-
-`rendcommon.c`
-: Parts of the onion service protocol that are shared by clients,
-services, and/or Tor servers.
-
-`rendmid.c`
-: Tor-server-side implementation of the onion service protocol. (Handles
-acting as an introduction point or a rendezvous point.)
-
-`rendservice.c`
-: Service-side implementation of the onion service protocol.
-
-`replaycache.c`
-: Backend to check introduce2 requests for replay attempts.
-
-
-### Authority modules ###
-
-`dircollate.c`
-: Helper for `dirvote.c`: Given a set of votes, each containing a list
-of Tor nodes, determines which entries across all the votes correspond
-to the same nodes, and yields them in a useful order.
-
-`dirvote.c`
-: Implements the directory voting algorithms that authorities use.
-
-`keypin.c`
-: Implements a persistent key-pinning mechanism to tie RSA1024
-identities to ed25519 identities.
-
-### Miscellaneous modules ###
-
-`control.c`
-: Implements the Tor controller protocol.
-
-`cpuworker.c`
-: Implements the inner work queue function.  We use this to move the
-work of circuit creation (on server-side) to other CPUs.
-
-`fp_pair.c`
-: Types for handling 2-tuples of 20-byte fingerprints.
-
-`geoip.c`
-: Parses geoip files (which map IP addresses to country codes), and
-performs lookups on the internal geoip table.  Also stores some
-geoip-related statistics.
-
-`policies.c`
-: Parses and implements Tor exit policies.
-
-`reasons.c`
-: Maps internal reason-codes to human-readable strings.
-
-`rephist.c`
-: Tracks Tor servers' performance over time.
-
-`status.c`
-: Writes periodic "heartbeat" status messages about the state of the Tor
-process.
-
-`transports.c`
-: Implements management for the pluggable transports subsystem.
