       _i_._t_a_p_e_._t_m_._f_a_s_t is a program that extracts TM imagery  from
       tape  media  with  different  blocking  factors (its value
       indicates how many rows are  combined  into  one  physical
       record on the tape).


       _i_._t_a_p_e_._t_m_._f_a_s_t must be run in a LOCATION_NAME with a (x,y)
       coordinate system (i.e., a coordinate system with  projec-
       tion  0).  For  further	information  regarding	the LOCA-
       TION_NAME type, please refer to the _i_m_a_g_e_r_y manual  entry.


       _i_._t_a_p_e_._t_m_._f_a_s_t  reads  the blocking factor from the header
       file as well as other parameters, such as gains	and  off-
       sets  for  each	band,  map  projection, sun elevation and
       azimuth, etc., and writes  into	history  file  (depending
       upon the contents of the header file).

OOPPTTIIOONNSS
       This program can be run either non-interactively or inter-
       actively. It will be run  non-interactively  if	the  user
       specifies  the  name  of  input device, the name of output
       group file, bands to be extracted,  and	optionally  other
       parameters (see below) on the command line using the form:


       ii..ttaappee..ttmm..ffaasstt	 hheellpp	 [--qq]	 iinnppuutt==_n_a_m_e    ggrroouupp==_n_a_m_e
       bbaannddss==_v_a_l_u_e[,_v_a_l_u_e,...]		  [rroowwss==_f_i_r_s_t_r_o_w_-_l_a_s_t_r_o_w]
       [ccoollss==_f_i_r_s_t_c_o_l_-_l_a_s_t_c_o_l] [TTIITTLLEE==_n_a_m_e]

       where the _i_n_p_u_t should be the device  name  on  which  the
       tape  media  are  mounted.  The	_g_r_o_u_p is an imagery group
       which will store the  extracted	TM  imagery.   The  _b_a_n_d_s
       value  in a list separated by commas is the bands the user
       wants to extract from the imagery. The _r_o_w_s and _c_o_l_s  rep-
       resent  the region which the user wishes to extract, where
       the default is whole imagery.  At last an  optional  _T_I_T_L_E
       is  for information only.  Alternatively, the program will
       be   run   interactively   if   the   user   types    only
       _i_._t_a_p_e_._t_m_._f_a_s_t;	in  this case the program will prompt the
       user for parameter values using the standard GRASS  _p_a_r_s_e_r
       interface.

       Running in command line mode,  _i_._t_a_p_e_._t_m_._f_a_s_t  will  over-
       write  the  group file and support files without prompting
       if the files existed.
