Usage of the eval_st (EVAL_ST) command-line oriented user interface to
evaluate transient ST segment episode detectors:

To write following text:

   eval_st -h

To evaluate an algorithm using a single record of a database:

   eval_st -r <database>_<algorithm>.evl <record> -[s|i]

           <database>_<algorithm>.evl is the evaluation project file,
           where <database> is database used and <algorithm> is the
           algorithm evaluated

   -r      Performs evaluation of the algorithm <algorithm> using the
           selected record <record> of the database <database>

   -s      All the episodes are considered as episodes of single type

   -i      Ischemic and non-ischemic heart-rate related episodes are 
           differentiated

   Examples:

       eval_st -r ltstb_alg02.evl s20011 -s

       Generates performance evaluation statistics for the record s20011
       while all the episodes are considered as episodes of single type

       eval_st -r ltstb_alg02.evl s20011 -i

       Generates performance statistics using the record s20011 for the
       ischemic episodes

To evaluate an algorithm using an entire database:

   eval_st -a <database>_<algorithm>.evl -[s|i] [-e|-b [NR_TRIALS]]

           <database>_<algorithm>.evl is the evaluation project file,
           where <database> is database used and <algorithm> is the
           algorithm evaluated

           One of the options -s or -i has to be used but only one at
           one time. Only one of the options -e or -b can be used in one
           time.

   -a      Performs aggregate statistics and record-by-record statistics
           for the algorithm <algorithm> using the selected database
           <database>

   -s      All the episodes are considered as episodes of single type

   -i      Ischemic and non-ischemic heart-rate related episodes are 
           differentiated

   -b [NR_TRIALS] Performs the bootstrap evaluation using NR_TRIALS
           bootstrap trials (default is 10000)

   -e      Performs evaluation of ST segment deviation measurements

   Examples:

       eval_st -a ltstb_alg02.evl -s

       Generates aggregate statistics and record-by-record statistics
       while all the episodes are considered as episodes of single type

       eval_st -a ltstb_alg02.evl -i

       Generates aggregate statistics and record-by-record statistics
       for ischemic episodes

       eval_st -a ltstb_alg02.evl -s -b

       Generates aggregate statistics and record-by-record statistics,
       and performs the bootstrap evaluation while all the episodes are
       considered as episodes of single type

       eval_st -a ltstb_alg02.evl -s -e

       Generates aggregates statistics and record-by-record statistics,
       and performs evaluation of ST segment deviation measurements
