CodingStyle

-Coding style
-============
-* Indentation: TAB (8 spaces width)
-* Braces: K&R, 1TBS
-* Max line width: 80 chars
-* Pointer asterisk attached to the name of the variable
-* Own structures/types: _t suffix (f.e. nameserver_t)
-* Header guard format: _KNOTD_HEADER_H_
-* Spaces around binary operators
-* Space between keyword and bracket (f.e. "if (predicate)")
-* No space between variable and typecast (f.e. "return (int)val;")
-
-To sum it up, Linux KNF is used, see [1].

-AStyle command format
-=====================
-astyle --style=1tbs -t8 -w -p -H -U -j --align-pointer=name
-
-Doxygen
-=======
-* Format: Qt-style
-  * "\brief", not "@brief"
-  * "/*!", not "/**"
-* Order of sections
-  * brief description
-  * long description
-  * notes
-  * warnings
-  * parameters
-  * return values
-  * todos
-* Always use \brief (no autobrief)
-* Indent text (using spaces only) in multiple-line sections
-* In multi-line comments, opening line (/*!) should be empty
-* One empty line between two consecutive sections
-* Struct and union members documented on the same line if the comment fits
-* Use \retval (or more of them) instead of \return
-  if the function returns some distinct values
-  (such as 0 for no error, -1 for something else, etc.)

-Knot is an open-source, high-performace, purely authoritative DNS server.
-
-<h2>Features</h2>
-
-Knot DNS supports the following DNS features:
-- TCP/UDP protocols
-- AXFR - master, slave
-- IXFR - master (primary master experimental), slave
-- TSIG
-- ENDS0
-- DNSSEC, including NSEC3
-- NSID
-- Unknown RR types
-
-Server features:
-- Adding/removing zones on-the-fly
-- Reconfiguring server instance on-the-fly
-- IPv4 / IPv6 support
-- Semantic checks of zones
-
-<h2>Compiling and running the server</h2>
-
-See the User manual - links to current version are provided in the
-<a href="https://git.nic.cz/redmine/projects/knot-dns/wiki">Knot DNS Wiki</a>.
-
-Alternatively you can generate the manual from the sources in Info format:

KNOWN_ISSUES

-Features not supported
-======================
-
-Here is a list of the most notable features that are not supported in the
-current version of Knot.
-
-* Other DNS classes than IN, partially CH (CS, HS)
-* Dynamic updates with signed zones have following limitations:
-  - Knot DNS doesn't automatically sign incoming RRs
-  - Removing of RRSIG without covered type specification
-  - Deleting a last RR also removes its RRSIG
-
-Known bugs
-==========
-
-* ACL may not always find the best match so it may behave counter-intuitively.
