There was some inconsistency between items being tagged as freeware versus open source. For the purposes of this page, freeware refers to proprietary software that has a license allowing free re-distribution of the binary but without access to the source and/or lacking a permissive distribution license of the source.
Most open source software listed here does provide free binaries (instead of just the source). If this is not the case for a particular program then a note can be made. -- JustinHannigan
