Using getopts to process long and short command line options

I wish to have long and short forms of command line options invoked using my shell script.

I know that getopts can be used, but like in Perl, I have not been able to do the same with shell.

Any ideas on how this can be done, so that I can use options like:

./shell.sh --copyfile abc.pl /tmp/./shell.sh -c abc.pl /tmp/

In the above, both the commands mean the same thing to my shell, but using getopts, I have not been able to implement these?
