+Besides standard `%s` placeholders inside the format string, you can use
+other custom ones, which help formatting common values faster:
+
+  * `%[file]s` --- absolute file name ➜ file name relative to current directory
+  * `%[text]s` --- any string ➜ pretty looking text, short enough, and escaped
+  * `%[exception]s` --- `Exception` ➜ stacktrace
+  * `%[list]s` --- `Iterable` ➜ pretty formatted list, in one line
+  * `%[size]s` --- size in bytes ➜ Kb, Mb, Gb, Tb, and so on
+  * `%[msec]s` --- milliseconds ➜ ms, sec, min, hours, etc.
+  * `%[nano]s` --- nanoseconds ➜ µs, ms, sec, min, hours, etc.
+  * `%[type]s` --- `Class<?>` ➜ name of it
+  * `%[secret]s` --- any string ➜ stars
+
+You are welcome to suggest your own "decors".
