  =head1 SYNOPSIS
  
  	mergectm2rttm.pl -r rttmfile -c ctmfile [ -p pathtools ]
  
  =head1 DESCRIPTION
  
  The script is a script which merged a ctm file and a rttm file to produce a rttm file. It takes in input a ctm file containing the lexemes information and a rttm file containing the speakers and segments information. It associates the lexemes and speakers present in the ctm according to the segments definitions from the rttm file (by segment definition, it means time intervals, filename and channel).
  
  =head1 USAGE
  
  Examples:
  
  	align2html-main.pl -r file.rttm -c file.ctm > mergedfile.rttm

  =head1 BUGS
  
  No known bugs.
  
  =head1 NOTES
  
  As the script requires two other scripts: rttmSmooth.pl and rttmSort.pl, the path of the SCTK tools directory can be specified on the commandline using the '-p' option.
  
  The script checks if the two scripts are present and run the merging process.
  To avoid any complication, there are 3 options to run the script:
  (a) Run the script into its directory without the -p option,
  (b) Run the script from any location by specifying the path with -p and the  path of the SCTK tools directory (.../stck/src/),
  (c) Edit the mergectm2rttm.pl line at line 184 and 185 to give the locations of the two scripts.
  
  The resulting rttm file is displayed in the standard output (STDOUT), by doing the redirection '>', it can be stored into a file.
