Hi,

Based on the last FASTK tool wrapper developed by @abueg in #5550 I have made necessary changes and updated the wrapper. The idea forward would be to create standalone suite of tools (Logex,Histex,etc) that exist within FASTK.

Best,
Saim

Other than fixing the shed.yml I think the first tool is read to be shipped.

Apart from the small change to the help this looks good to go from my side. Thanks a lot to all who contributed.

@SaimMomin12 for downstream tools, the hidden ktab files are required, and a consistent naming schema is also important. Would it be possible to add those into the output structure?

Hi @astrovsky01, yes the earlier day I realized that the ktab files are necessary while I was working on Logex tool. I will figure out a way to retain these files and update the wrapper accordingly.
