+# Why
+
+Since [`ncurses` 6.1](https://www.gnu.org/software/ncurses/#h3-programs)
+
+`tic` and `infocmp` display numeric values in hexadecimal when they are "close"
+to a power of two, "making the result more readable". This causes issues for
+`sbt` and and other programs using `jline < 2.14.4`. This package aims to
+provide a fix for that.
+
+## ncurses-nohex
+
+The `ncurses-nohex` package applies a patch that undo this functionality. The
+package replaces ncurses in full.
+
+## infocmp-nohex
+
+`infocmp-nohex` works with any build of ncurses by installing the `infocmp`
+binary to /usr/local/bin, effectively shadowing the normal infocmp. It's a bit
+of a hack but it works.
