I once worked for a company that had a product which had a fairly complicated and time-consuming build process. Someone had written a distributed build process using the traditional CMD.exe shell scripting language. It was running multiple processes in parallel, and they communicated by writing and reading text files. Later they added PowerShell scripts. All in all, there were tens of thousands of lines of PS and BAT scripts. It was quite a nightmare. The team was supposed to maintain this mess. We decided to create a compiler that translated .BAT scripts to C#. The idea was that the C# code would be easier to understand and modify. I left before it was complete, so I'm not sure how that worked out. But last I heard, they were pleased that some parts of it now ran thousands of times faster.
