most ghey software: PVCS Dimensions from Merant
its a source control software which costs about US$1400, it is very powerful but suffers badly from one major flaw: you cannot enter 2 files with the same file name into the system!!

this is a major problem when developing web applications because they all involve a lot of common files, such as web.xml, index.jsp, struts-config.xml, application.properties, build.xml.

in other words we can only store one of our many web apps in this stupid source control. the only way to add more is to rename every file when we check it in and out. i.e. eBanking.web.xml. which most certainly teh ghey.
