Hamilton Laboratories is an independent software vendor of tools for software developers.  We are the developer and publisher of Hamilton C shell, a complete recreation of the UNIX csh shell and the numerous popular UNIX utilities such as grep, fgrep, head, tail, diff, sed, cron, tar, etc. The result is a much faster, more powerful command line environment than the standard Windows command prompt.  The entire product was written from scratch for Windows by a single author.
