NAME

       extend -- produce an extended elevation from a .3d file

SYNOPSIS

       extend [--specfile configuration .espec file]   input .3d file [output .3d file]

Description
	      Note:

	      The extend program can also work on Compass .plt (as can aven and any other Survex program which reads .3d files).

       If  no  specfile  is  given,  extend  starts  with  the highest station marked as an entrance which has at least one underground survey leg
       attached to it.	If there are no such stations, the highest deadend station in the survey (or the highest station if there are no deadends)
       is used.  Extend puts the first station on the left, then folds each leg out individually to the right, breaking loops arbitrarily (usually
       at junctions).

       If the output filename is not specified, extend bases the output filename on the input filename, but  ending  "_extend.3d".   For  example,
       extend deep_pit.3d produces an extended elevation called deep_pit_extend.3d.

       This approach suffices for simple caves or sections of cave, but for more complicated situations human intervention is required.  More com-
       plex sections of cave can be handled with a specfile giving directions to switch the direction of extension  between  left  and	right,	to
       explicitly specify the start station, or to break the extension at particular stations or legs.

       The specfile is in a format similar to cavern's data format:

       ;This is a comment

       ; start the elevation at station entrance.a
       *start entrance.a  ;this is a comment after a command

       ; start extending leftwards from station half-way-down.5
       *eleft half-way-down.5

       ; change direction of extension at further-down.8
       *eswap further-down.8

       ; extend right from further-down.junction, but only for
       ; the leg joining it to very-deep.1, other legs continuing
       ; as before
       *eright further-down.junction  very-deep.1

       ; break the survey at station side-loop.4
       *break side-loop.4

       ; break survey at station side-loop.junction but only
       ; for leg going to complex-loop.2
       *break side-loop.junction complex-loop.2

       This  approach  requires  some  trial  and  error, but gives useful results for many caves.  The most complex systems would benefit from an
       interactive interface to select and view the breaks and switches of direction.

       };

CONSTANTS

       WLAN_STA_AUTH
	   Station is authenticated.

       WLAN_STA_ASSOC
	   Station is associated.

       WLAN_STA_PS_STA
	   Station is in power-save mode

       WLAN_STA_AUTHORIZED
	   Station is authorized to send/receive traffic. This bit is always checked so needs to be enabled for all stations when virtual port
	   control is not in use.

       WLAN_STA_SHORT_PREAMBLE
	   Station is capable of receiving short-preamble frames.

       WLAN_STA_WME
	   Station is a QoS-STA.

       WLAN_STA_WDS
	   Station is one of our WDS peers.

       WLAN_STA_CLEAR_PS_FILT
	   Clear PS filter in hardware (using the IEEE80211_TX_CTL_CLEAR_PS_FILT control flag) when the next frame to this station is transmitted.

       WLAN_STA_MFP
	   Management frame protection is used with this STA.

       WLAN_STA_BLOCK_BA
	   Used to deny ADDBA requests (both TX and RX) during suspend/resume and station removal.

       WLAN_STA_PS_DRIVER
	   driver requires keeping this station in power-save mode logically to flush frames that might still be in the queues

       WLAN_STA_PSPOLL
	   Station sent PS-poll while driver was keeping station in power-save mode, reply when the driver unblocks.

       WLAN_STA_TDLS_PEER
	   Station is a TDLS peer.

       WLAN_STA_TDLS_PEER_AUTH
	   This TDLS peer is authorized to send direct packets. This means the link is enabled.

       WLAN_STA_UAPSD
	   Station requested unscheduled SP while driver was keeping station in power-save mode, reply when the driver unblocks the station.

       WLAN_STA_SP
	   Station is in a service period, so don't try to reply to other uAPSD trigger frames or PS-Poll.

       WLAN_STA_4ADDR_EVENT
	   4-addr event was already sent for this frame.

       WLAN_STA_INSERTED
	   This station is inserted into the hash table.

       WLAN_STA_RATE_CONTROL
	   rate control was initialized for this station.

       WLAN_STA_TOFFSET_KNOWN
	   toffset calculated for this station is valid.

       WLAN_STA_MPSP_OWNER
	   local STA is owner of a mesh Peer Service Period.

       WLAN_STA_MPSP_RECIPIENT
	   local STA is recipient of a MPSP.

DESCRIPTION

       These flags are used with struct sta_info's flags member, but only indirectly with set_sta_flag and friends.
