+QUICK INSTALL GUIDE
+
+drill is a subdirectory in ldns.
+
+To compile drill you need:
+autoreconf && ./configure && make
+
+If ldns is installed in a different location, use --with-ldns=directory
+See also ./configure --help
+
+In the first case you must run drill as:
+LD_LIBRARY_PATH=../.libs ./drill <options>

+REGRESSIONS
+
+This version of drill is based on ldns and as such some things
+are slightly changed. This file documents the changes.
+
+o When tracing (-T option) we use the local resolver (as specified
+  in /etc/resolv.conf) to lookup names. This increases the speed
+  dramatically, but you obviously need to be able to reach a recursive
+  server/cache.
+  Previously drill would try to resolve the names by itself.
+
+o Printing of DSs after DNSKEY records. Because we don't parse our
+  own packets anymore, we cannot print the DS directly after the DNSKEY 
+  record. The DSs are now printed AFTER the packet.
+
+o The long options are removed.
+
+o The chase function has a different output, and will be subject to change
+  in the near future.
+ 
+o The useless (for jokes only) -I option was dropped.
+
+FIXED:
+o the argument parsing is much smarter, the order doesn't matter (much)
+  anymore

+\`configure' configures ldns 1.6.13 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.SH NAME
+drill \- get (debug) information out of DNS(SEC)
+.SH SYNOPSIS
+.B drill
+[
+.IR OPTIONS
+]
+.IR name
+[
+.IR @server
+]
+[
+.IR type
+]
+[
+.IR class
+]
+
+.SH DESCRIPTION
+\fBdrill\fR is a tool to designed to get all sorts of information out of the
+DNS. It is specificly designed to be used with DNSSEC. 
+.PP
+The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able
+get even more information than with \fBdig\fR.
+.PP
+If no arguments are given class defaults to 'IN' and type to 'A'. The
+server(s) specified in /etc/resolv.conf are used to query against.
+
+.PP
+\fIname\fR
+Ask for this name.
+
+.PP
+\fI@server\fR
+Send to query to this server. If not specified use the nameservers from
+\fI/etc/resolv.conf\fR.
+
+.PP
+\fItype\fR
+Ask for this RR type. If type is not given on the command line it defaults
+to 'A'. Except when doing to reverse lookup when it defaults to 'PTR'.
+
+.PP
+\fIclass\fR
+Use this class when querying.
+
+.SH SAMPLE USAGE
+\fBdrill mx miek.nl\fR
+Show the MX records of the domain miek.nl
+
+.TP
+\fBdrill -S jelte.nlnetlabs.nl\fR
+Chase any signatures in the jelte.nlnetlab.nl domain. This option is
+only available when ldns has been compiled with openssl-support.
+
+.TP
+\fBdrill -TD www.example.com\fR
+Do a DNSSEC (-D) trace (-T) from the rootservers down to www.example.com.
+This option only works when ldns has been compiled with openssl support.
+
+.TP
+\fBdrill -s dnskey jelte.nlnetlabs.nl\fR
+Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY
+record also print the DS record.
+
+.SH OPTIONS
+
+.TP
+\fB\-D
+Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG,
+DS and NSEC) this is \fInot\fR automaticly enabled.
+
+.TP
+\fB\-T
+Trace \fIname\fR from the root down. When using this option the @server and
+the type arguments are not used.
+
+.TP
+\fB\-S
+Chase the signature(s) of 'name' to a known key or as high up in
+the tree as possible.
+
+.TP
+\fB\-V \fIlevel\fR
+Be more verbose. Set level to 5 to see the actual query that is sent.
+
+.TP
+\fB\-Q
+Quiet mode, this overrules -V. 
+
+.TP
+\fB\-f \fIfile\fR
+Read the query from a file. The query must be dumped with -w. 
+
+.TP
+\fB\-i \fIfile\fR
+read the answer from the file instead from the network. This aids
+in debugging and can be used to check if a query on disk is valid.
+If the file contains binary data it is assumed to be a query in
+network order.
+
+.TP
+\fB\-w \fIfile\fR
+Write an answer packet to file.
+
+.TP
+\fB\-q \fIfile\fR
+Write the query packet to file.
+
+.TP
+\fB\-v
+Show drill's version.
+
+.TP
+\fB\-h
+Show a short help message.
+
+.SS QUERY OPTIONS
+
+.TP
+\fB\-4
+Stay on ip4. Only send queries to ip4 enabled nameservers.
+
+.TP
+\fB\-6
+Stay on ip6. Only send queries to ip6 enabled nameservers.
+
+.TP
+\fB\-a
+Use the resolver structure's fallback mechanism if the answer
+is truncated (TC=1). If a truncated packet is received and this
+option is set, drill will first send a new query with EDNS0 
+buffer size 4096.
+
+If the EDNS0 buffer size was already set to 512+ bytes, or the
+above retry also results in a truncated answer, the resolver
+structure will fall back to TCP.
+
+.TP
+\fB\-b \fIsize\fR
+Use size as the buffer size in the EDNS0 pseudo RR.
+
+.TP
+\fB\-c \fIfile\fR
+Use file instead of /etc/resolv.conf for nameserver configuration.
+
+.TP
+\fB\-d \fIdomain\fR
+When tracing (-T), start from this domain instead of the root.
+
+.TP
+\fB\-t
+Use TCP/IP when querying a server
+
+.TP
+\fB\-k \fIkeyfile\fR
+Use this file to read a (trusted) key from. When this options is
+given \fBdrill\fR tries to validate the current answer with this
+key. No chasing is done. When \fBdrill\fR is doing a secure trace, this
+key will be used as trust anchor. Can contain a DNSKEY or a DS record.
+
+.TP
+\fB\-o \fImnemonic\fR
+Use this option to set or unset specific header bits. A bit is
+set by using the bit mnemonic in CAPITAL letters. A bit is unset when
+the mnemonic is given in lowercase. The following mnemonics are
+understood by \fBdrill\fR:
+
+        QR, qr: set, unset QueRy (default: on)
+        AA, aa: set, unset Authoritative Answer (default: off)
+        TC, tc: set, unset TrunCated (default: off)
+        RD, rd: set, unset Recursion Desired (default: on)
+        CD, cd: set, unset Checking Disabled  (default: off)
+        RA, ra: set, unset Recursion Available  (default: off)
+        AD, ad: set, unset Authenticated Data (default: off)
+
+Thus: \fB-o CD\fR, will enable Checking Disabled, which instructs the 
+cache to not validate the answers it gives out.
+
+.TP
+\fB\-p \fIport\fR
+Use this port instead of the default of 53.
+

+\fB\-r \fIfile\fR
+When tracing (-T), use file as a root servers hint file.
