Which values do I build my newly founded company on? There are many things I value highly - fairness, professionalism, quality, innovation, honesty - but one thing stands out: sharing. The IT community as I have come to know it is centered around the wish to help others by sharing information and software. I want to live with and support this community, and I will do that by sharing myself, both information and software. I have blogged, spoken, tweeted and developed free tools in the past, and I will continue to do so. I will even share what little knowledge I have of funding and running a software and consulting company, and I am going to start doing that right here.

It seems the Citrix community had only had one topic recently, albeit one discussed hotly: licensing. Now that Citrix has given in and practically allowed all conceivable license types, everybody is happy?! It seems so, although CCU licenses have doubled in price, as Shawn Bass points out. But is this really the happy ending of a short but wild story? Maybe, maybe not. Let me explain.

A few weeks ago I published the tool ParseCitrixLicense which displays the contents of Citrix license files in a human-readable form. The original version 1.0 did not support XenDesktop licenses, for the simple reason that I had none to test my program with. Recently my colleague Nicholas Dille provided me with a XenDesktop eval license which I used to implement the missing tags in ParseCitrixLicense. Please see for yourself what ParseCitrixLicense extracts from a XenDesktop license file.

Update: Version 1.1 supports XenDesktop Licenses in Addition to XenApp Licenses Most Citrix products rely heavily on license files. While the basic format of a license file is somewhat documented, most fields used in license files are not. This makes understanding their contents difficult. It does not help that the license files can hardly be called readable with most of the relevant data in one long line.
