    My thanks for your gifts.

  • Public References - I enjoy being known as a contributor to the open-source community. If you give any papers or presentations, please reference and place on your plots the Orca logo. If you have public web pages, please add the Orca logo and link it to the Orca web site.

  • Public Web Page - Putting a public web page up with some or all of your Orca statistics and emailing me the link. I'll add a link on my site to your site if it is appropriate for you. I know some of this data can be sensitive information, but seeing more sites using Orca always helps motivate me :)


Latest stable versions:

The Orca package contains the Orca Perl script and all of the data gathering programs, i.e. orcallator.se and procallator.se. However, orcallator.se is sometimes updated more frequently than Orca and separate orcallator.se's are listed here.

Latest development snapshot:

Source code management system:

  • OrcaWare has a Subversion server that hosts all of the source code. This is the preferred means of checking out code, making modifications and submitting them back to the main source code repository.
