-generic cli timestamp parser and calculator tool
+I am not developing  this tool any further. The reasons
+are  that the  underlying modules  are all  not actively  maintained
+anymore and the tool was way too  us centric and most of my personal
+requirements for time/date calculatons were not met.
+
+However, I am now developing another  tool for the same purpose, but
+this time not using arbitrary  natural language but following a more
+generic  aproach using  the [expr  language](https://expr-lang.org/)
+with my own custom operators and functions.
+
+[Check it out: tica](https://codeberg.org/scip/tica)!
