       This  program imports Census line features from TIGER records type1 and
       type2 into GRASS vector format.	Both pre-Census and  post-Census  data
       formats can be used.  Specific Census Feature Class Codes (CFCC) can be
       extracted completely or	in  various  combinations.   These  codes  are
       described  in  the TIGER/line Census Files 1990 documemtation available
       from the Bureau of the Census.  An additional feature  code  consisting
       of  the	three  letters "BOU" may also be specified to extract a county
       boundary.  Condensed Record 1 files may be imported with the  -c  flag.
       These  files  should be identified with a trailing "x" character on the
       filename.

       To extract all Primary (A1) and Secondary (A2) roads  from  a  county's
       TIGER files the following command would be used:



	vv..iinn..ttiiggeerr..ssccss ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==roads
	      ccffcc==A1,A2


       To extract all the Hydrographic features in a county's TIGER files with
       verbose output:



	vv..iinn..ttiiggeerr..ssccss --vv ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==hydro
	      ccffcc==H


       To extract the county boundary the command would be:



	vv..iinn..ttiiggeerr..ssccss ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==bou
	      ccffcc==BOU



NNOOTTEESS
       The TIGER files must in sorted order before being used.	 This  can  be
       done by using the following command:

	    sort TGR12113.F21 -o t12113.1
	    sort TGR12113.F22 -o t12113.2

       For  consistency the sorted file should be written as above.  It should
       consist of a 't' followed by the State and County FIPS code, then a '.'
       and then a value to identify the record number.


       The  CFCC code 'BOU' used to extract the County Boundary should be used
       alone as it will result in a polygon AREA being created.


       Currently output is in UTM only.
