%  PROGRAM
% cknn_printsig - Print a K-Nearest Neighbors Signature
%
%  DESCRIPTION
% This operator prints out the contents of a K-Nearest Neighbors Signature file created with "cknn_signature". It expects a valid K-Nearest Neighbors signature in the parameter [-isig] so its input must be either the output of a \fIcknn_signature\fP or the output of \fIcsigappend\fP which can be used to append signatures of variable size. Its output can be formatted so it can be used in reports, etc. and will be redirected to kstdout unless a file name is passed with the parameter [-o].
% The output of this program can be in four formats, depending on the value of the parameter [-omode] :
% The Text (ASCII) format option ([-omode 1]) formats the output so it can be viewed with simple text editors or in kstdout.
% The LaTeX format option ([-omode 2]) formats the output so it can be included in a LaTeX file with the \\input command.
% The HTML format option ([-omode 3]) formats the output in a HTML table so it can be read into a HTML file.
% The CSV format option ([-omode 4]) formats the output in a Comma-delimited format so it can be read by spreadsheets, etc.
% One of the problems with the generation of LaTeX tables is that a single table is generated, and if there are too many signatures in the input the table will be too big to be displayed in a single page. In this case the user must edit the .tex file and break the table manually.
