# File: svcconf-convert.pl:
# Purpose: This perl script convert classic svc.conf file into XML svc.conf file format.
# Usage: svcconf-convert.pl [-i infile] [-o outfile] [-verbose] [-nocomment]
#           -i: Specify the input classic svc.conf filename.
#               If omitted, the default input filename is "svc.conf".
#           -o: Specify the output XML svc.conf filename.
#               If this argument is omitted, the resulting XML file will be written
#               to file called <input filename>.xml.
#           -verbose: Verbose output.
#           -nocomment: Remove all comments.  Use this argument if you have comments
#                       mixing in the middle of a classic svc.conf directive.
