#==================================================================
#
# parseSQL.pl
#
# Parses a Dynamic SQL snapshot, outputs the report lines in delimited
# ascii format so that is can be read into a spread sheet
# for analysis and sorting of the output.
#
# USAGE:
# parseSQL.pl input-file "string to start a new row in the output file"
# match_character output-file
#
# e.g. parseSQL.pl dynsql.out "^ Number of executions" = > temp.out
# The above commands will open and parse the file dynsql.out
# and write the information on the right side of the '='
# and write a new line each time it finds "^ Number of executions"
#
# example command
# perl parseSQL.pl sql.snap "^ Number of executions" = > temp.txt
#
