DDEESSCCRRIIPPTTIIOONN
This program prints the header of _R_L_E(5) files in a human
readable form. If the optional _f_i_l_e_s argument is not sup
plied, input is read from standard input.

--bb Print the information in a "brief" one-line form.
The form of the output line is
_n_a_m_e: [_l,_b]+[_x_s,_y_s]x_n_c+A, BG=_c_o_l_o_r, map=_Nx_L, (C)
Where [_l,_b] is the position of the lower-left cor
ner of the image, [_x_s,_y_s] is the size of the image
in pixels, _n_c is the number of channels saved, +A
is present if an alpha channel is saved. BG= or
OV= indicate that a background color was saved; OV=
means that the existing background is not cleared
to the background color before the image is read
(this was used for a cheap form of compositing, but
is basically obsolete now). _c_o_l_o_r is the saved
background color. The map= entry will be present
only if a color map was saved; _N is the number of
channels in the color map and _L is the length of
the map. Finally (C) is appended if there are com
ments present.
--cc _c_o_m_m_e_n_t_-_n_a_m_e_s
If a comment identified by any of the words in the
comma-separated list _c_o_m_m_e_n_t_-_n_a_m_e_s is present in
the input file, its first line will be printed.
Each name is tried, in turn, and only the first
match is printed. If no match is found, but com
ments are present, (C) will be printed. The --cc
flag implies --bb.
--dd Dump a very verbose version of the image contents
as text to the standard error output stream.
--mm Print out the color map information. --vv Prints the
raster toolkit version and patch level. No input
files will be processed if this option is given.
