-.SH DESCRIPTION
-These functions create and manipulate a balanced binary (AVL) tree.  Each node
-of the tree contains the expected left & right subtree pointers, a short int
-balance indicator, and a pointer to the user data.  On a 32 bit system, this
-means an overhead of 4+4+2+4 bytes per node (or, on a RISC or otherwise
-alignment constrained system with implied padding, 4+4+4+4 bytes per node).
-There is no key data type enforced by this package; a caller supplied
-compare routine is used to compare user data blocks.
-.PP
-Balanced binary trees are very fast on searches and replacements, but have a
-moderately high cost for additions and deletions.  If your application does a
-lot more searches and replacements than it does additions and deletions, the
-balanced (AVL) binary tree is a good choice for a data structure.
-.PP
-.I Tree_init
-creates an empty tree and binds it to
-.I tree
-(which for this and all other routines in this package should be declared as
-a pointer to void or int, and passed by reference), which can then be used by
-other routines in this package.  Note that more than one
-.I tree
-variable can exist at once; thus multiple trees can be manipulated
-simultaneously.
-.PP
-.I Tree_srch
-searches a tree for a specific node and returns either
-.I NULL
-if no node was found, or the value of the user data pointer if the node
-was found.
-.I compare
-is the address of a function to compare two user data blocks.  This routine
-should work much the way 
-.IR strcmp (3)
-does; in fact,
-.I strcmp
-could be used if the user data was a \s-2NUL\s+2 terminated string.
-.I data
-is the address of a user data block to be used by
-.I compare
-as the search criteria.  The tree is searched for a node where
-.I compare
-returns 0.
-.PP
-.I Tree_add
-inserts or replaces a node in the specified tree.  The tree specified by
-.I tree
-is searched as in
-.I tree_srch,
-and if a node is found to match
-.I data,
-then the
-.I del_uar
-function, if non\-\s-2NULL\s+2, is called with the address of the user data
-block for the node (this routine should deallocate any dynamic memory which
-is referenced exclusively by the node); the user data pointer for the node
-is then replaced by the value of
-.I data.
-If no node is found to match, a new node is added (which may or may not
-cause a transparent rebalance operation), with a user data pointer equal to
-.I data.
-A rebalance may or may not occur, depending on where the node is added
-and what the rest of the tree looks like.
-.I Tree_add
-will return the
-.I data
-pointer unless catastrophe occurs in which case it will return \s-2NULL\s+2.
-.PP
-.I Tree_delete
-deletes a node from
-.I tree.
-A rebalance may or may not occur, depending on where the node is removed from
-and what the rest of the tree looks like.
-.I Tree_delete
-returns TRUE if a node was deleted, FALSE otherwise.
-.PP
-.I Tree_trav
-traverses all of
-.I tree,
-calling
-.I trav_uar
-with the address of each user data block.  If
-.I trav_uar
-returns FALSE at any time,
-.I tree_trav
-will immediately return FALSE to its caller.  Otherwise all nodes will be 
-reached and
-.I tree_trav
-will return TRUE.
-.PP
-.I Tree_mung
-deletes every node in
-.I tree,
-calling
-.I del_uar
-(if it is not \s-2NULL\s+2) with the user data address from each node (see
-.I tree_add
-and
-.I tree_delete
-above).  The tree is left in the same state that
-.I tree_init
-leaves it in \- i.e., empty.
-.SH BUGS
-Should have a way for the caller to specify application specific
-.I malloc
-and
-.I free
-functions to be used internally when allocating meta data.

-.SH NAME
-nslookup \- query Internet name servers interactively
-.SH SYNOPSIS
-.B nslookup
-[ 
-.I \-option ...
-]
-[
-.I host-to-find
-| \- [
-.I server
-]] 
-.SH DESCRIPTION
-.I Nslookup
-is a program to query Internet domain name servers. 
-Nslookup has two modes: interactive and non-interactive.
-Interactive mode allows the user to query name servers for
-information about various hosts and domains or to print a list of hosts 
-in a domain. 
-Non-interactive mode is used to print just the name and requested information
-for a host or domain.
-.sp 1
-.SH ARGUMENTS
-Interactive mode is entered in the following cases:
-.IP a) 4
-when no arguments are given (the default name server will be used),
-.IP b) 4
-when the first argument is a hyphen (\-) and the second argument
-is the host name or Internet address of a name server.
-.LP
-Non-interactive mode is used when the name or Internet address 
-of the host to be looked up
-is given as the first argument. The optional second argument specifies
-the host name or address of a name server.
-.LP
-The options listed under the ``set'' command below can be specified in
-the .nslookuprc file in the user's home directory if they are listed 
-one per line. Options can also be specified
-on the command line if they precede the arguments and are prefixed with
-a hyphen. For example, to change the default query type to host information,
-and the initial timeout to 10 seconds, type:
-.sp .5v
-	nslookup \-query=hinfo  \-timeout=10
-.sp .5v
-.SH "INTERACTIVE COMMANDS"
-Commands may be interrupted at any time by typing a control-C.
-To exit, type a control-D (EOF) or type exit.
-The command line length must be less than 256 characters.
-To treat a built-in command as a host name, 
-precede it with an escape character (\e). 
-\fBN.B.\fP an unrecognized command will be interpreted as a host name.
-.sp .5v
-.IP "\fIhost\fP [\fIserver\fP]"
-Look up information for \fIhost\fP using the current default server
-or using \fIserver\fP if specified.
-If \fIhost\fP is an Internet address and the query type is A or PTR, the 
-name of the host is returned.
-If \fIhost\fP is a name and does not have a trailing period, the default 
-domain name is appended to the name. (This behavior depends on the state of the
-\fBset\fP options \fBdomain\fP, \fBsrchlist\fP, 
-\fBdefname\fP, and \fBsearch\fP).
-To look up a host not in the current domain, append a period to 
-the name.
-.sp 1
-.IP "\fBserver\fP \fIdomain\fP"
-.ns
-.IP "\fBlserver\fP \fIdomain\fP"
-Change the default server to \fIdomain\fP. 
-\fBLserver\fP uses the initial server to look up 
-information about \fIdomain\fP while \fBserver\fP
-uses the current default server. 
-If an authoritative answer can't be found, the names of servers
-that might have the answer are returned.
-.sp 1
-.IP \fBroot\fP
-Changes the default server to the server for the root of the domain name space.
-Currently, the host ns.internic.net is used.
-(This command is a synonym for \fBlserver ns.internic.net.\fP)
-The name of the root server can be changed with the \fBset root\fP command.
-.sp 1
-.IP "\fBfinger\fP [\fIname\fP] [\fB>\fP \fIfilename\fP]"
-.ns
-.IP "\fBfinger\fP [\fIname\fP] [\fB>>\fP \fIfilename\fP]"
-Connects with the finger server on the current host. 
-The current host is defined when a previous lookup for a host
-was successful and returned address information (see the 
-\fBset querytype=A\fP command).
-\fIName\fP is optional. 
-\fB>\fP and \fB>>\fP can be used to redirect output in the
-usual manner.
-.sp 1
-.IP "\fBls\fR [\fIoption\fR] \fIdomain\fR [\fB>\fR \fIfilename\fR]"
-.ns
-.IP "\fBls\fR [\fIoption\fR] \fIdomain\fR [\fB>>\fR \fIfilename\fR]"
-List the information available for \fIdomain\fP, optionally creating
-or appending to \fIfilename\fP.
-The default output contains host names and their Internet addresses. 
-.I Option 
-can be one of the following:
-.RS
-.IP "\fB\-t \fIquerytype\fP" 4
-lists all records of the specified type (see \fIquerytype\fP below).
-.IP \fB\-a\fP 4
-lists aliases of hosts in the domain. 
-synonym for \fB\-t\ \ CNAME\fP.
-.IP \fB\-d\fP 4
-lists all records for the domain.
-synonym for \fB\-t\ \ ANY\fP.
-.IP \fB\-h\fP 4
-lists CPU and operating system information for the domain.
-synonym for \fB\-t\ \ HINFO\fP.
-.IP \fB\-s\fP 4
-lists well-known services of hosts in the domain.
-synonym for \fB\-t\ \ WKS\fP.
-.P
-When output is directed to a file, hash marks are printed for every
-50 records received from the server.
-.RE
-.sp 1
-.IP "\fBview\fP \fIfilename\fP"
-Sorts and lists the output of previous \fBls\fP command(s) with 
-\fImore\fP(@CMD_EXT@).
-.sp 1
-.ne 4
-.IP "\fBhelp\fP"
-.ns
-.IP "\fB?\fP"
-Prints a brief summary of commands.
-.sp 1
-.IP "\fBexit\fP"
-Exits the program.
-.sp 1
-.IP "\fBset\fP \fIkeyword\fP[=\fIvalue\fP]"
-This command is used to change state information that affects the lookups.
-Valid keywords are:
-.RS
-.IP "\fBall\fP"
-Prints the current values of the frequently-used options to \fBset\fP.
-Information about the  current default server and host is also printed.
-.IP "\fBclass=\fIvalue\fR"
-Change the query class to one of:
-.RS
-.IP IN 10
-the Internet class.
-.IP CHAOS 10
-the Chaos class.
-.IP HESIOD 10
-the MIT Athena Hesiod class.
-.IP ANY 10
-wildcard (any of the above).
-.P
-The class specifies the protocol group of the information.
-.br
-(Default = IN, abbreviation = cl)
-.RE
-.IP "\fB[no]debug\fP"
-Turn debugging mode on. A lot more information is printed about the
-packet sent to the server and the resulting answer.
-.br
-(Default = nodebug, abbreviation = [no]deb)
-.IP "\fB[no]d2\fP"
-Turn exhaustive debugging mode on.
-Essentially all fields of every packet are printed.
-.br
-(Default = nod2)
-.IP "\fBdomain=\fIname\fR"
-Change the default domain name to \fIname\fP. 
-The default domain name is appended to a lookup request depending on the
-state of the \fBdefname\fP and \fBsearch\fP options.
-The domain search list contains the parents of the default domain if it has 
-at least two components in its name. 
-For example, if the default domain
-is CC.Berkeley.EDU, the search list is CC.Berkeley.EDU and Berkeley.EDU.
-Use the \fBset srchlist\fP command to specify a different list.
-Use the \fBset all\fP command to display the list.
-.br
-(Default = value from hostname, /etc/resolv.conf or LOCALDOMAIN, 
-abbreviation = do)
-.IP "\fBsrchlist=\fIname1/name2/...\fR"
-Change the default domain name to \fIname1\fP and the domain search list
-to \fIname1\fP, \fIname2\fP, etc. A maximum of 6 names separated by slashes (/)
-can be specified.
-For example,
-.sp .5v
-    set\ srchlist=lcs.MIT.EDU/ai.MIT.EDU/MIT.EDU
-.sp .5v
-sets the domain to lcs.MIT.EDU and the search list to the three names.
-This command overrides the
-default domain name and search list of the \fBset domain\fP command.
-Use the \fBset all\fP command to display the list.
-.br
-(Default = value based on hostname, /etc/resolv.conf or LOCALDOMAIN, 
-abbreviation = srchl)
-.IP "\fB[no]defname\fP"
-If set, append the default domain name to a single-component lookup request 
-(i.e., one that does not contain a period).
-.br
-(Default = defname, abbreviation = [no]def)
-.IP "\fB[no]search\fP"
-If the lookup request contains at least one period but doesn't end 
-with a trailing period, 
-append the domain names in the domain search list
-to the request until an answer is received.
-.br
-(Default = search, abbreviation = [no]sea)
-.IP "\fBport=\fIvalue\fR"
-Change the default TCP/UDP name server port to \fIvalue\fP.

-RFC-1035 document.
-.br
-(Default = A, abbreviations = q, ty)
-.RE
-.IP "\fB[no]recurse\fP"
-Tell the name server to query other servers if it does not have the
-information.
-.br
-(Default = recurse, abbreviation = [no]rec)
-.IP \fBretry=\fInumber\fR
-Set the number of retries to \fInumber\fP. 
-When a reply to a request is not received within a certain 
-amount of time (changed with \fBset timeout\fP), 
-the timeout period is doubled and the request is resent. 
-The retry value controls how many times a request is resent before giving up.
-.br
-(Default = 4, abbreviation = ret)
-.IP \fBroot=\fIhost\fR
-Change the name of the root server to \fIhost\fP. This
-affects the \fBroot\fP command.

-If the lookup request was not successful, an error message is printed.
-Possible errors are:
-.IP "Timed out" 5
-The server did not respond to a request after a certain amount of
-time (changed with \fBset timeout=\fIvalue\fR) 
-and a certain number of retries (changed with \fBset retry=\fIvalue\fR).
-.IP "No response from server" 5
-No name server is running on the server machine.
-.IP "No records" 5
-The server does not have resource records of the current query type for the
-host, although the host name is valid.
-The query type is specified with the \fBset querytype\fP command.
-.IP "Non-existent domain" 5
-The host or domain name does not exist.
-.IP "Connection refused" 5
-.ns
-.IP "Network is unreachable" 5
-The connection to the name or finger server could not be made 
-at the current time.
-This error commonly occurs with \fBls\fP and \fBfinger\fP requests. 
-.IP "Server failure" 5
-The name server found an internal inconsistency in its database
-and could not return a valid answer.
-.IP "Refused" 5
-The name server refused to service the request.
-.IP "Format error" 5
-The name server found that the request packet was not in the proper format.
-It may indicate an error in \fInslookup\fP.
