+# TPB
+
+> Pronounced `tee pee bee` or `tee pasteboard`
+
+TPB is a super simple, small program to "tee" into my clipboard using OSC 52
+codes.
+
+> Usage: `command | tpb`
+
+I was somewhat fed up with `pbcopy` eating stdout making it impossible to see
+the output of what I was doing without pasting it. While, yes, this could just
+be a shell script, I decided to write in a systems language because its more fun
+and I like the idea of it being super low latency. Originally, I was going to
+write this in Rust but decided that Zig was a better fit for something like
+this.
