+- 'COLORED_STDERR_IGNORED_BINARIES'
+ Comma separated list of binary names/paths which should not be tracked
+ (including their children). Useful for `reset` which writes to the terminal
+ but fails to work if the output is colored. See below for an example.
+
+All environment variables starting with 'COLORED_STDERR_PRIVATE_*' are
+internal variables used by the implementation and should not be set manually.
+See the source for details.
+
+
+To set custom colors as pre/post strings you can use the `$''` feature of Bash
+and Zsh:
+
+ export COLORED_STDERR_PRE=$'\033[91m' # bright red
+ export COLORED_STDERR_POST=$'\033[0m' # default
+
+Or to be more compatible you can use the following which should work in any
+Bourne shell:
+
+ esc=`printf '\033'`
+ COLORED_STDERR_PRE="${esc}[91m" # bright red
+ COLORED_STDERR_POST="${esc}[0m" # default
+ export COLORED_STDERR_PRE COLORED_STDERR_POST
+
+Fix `reset`; its writes to the terminal must be unaltered. `reset` is a
+symbolic-link to `tset` on some systems, adapt as necessary:
+
+ COLORED_STDERR_IGNORED_BINARIES=/usr/bin/tset
+ export COLORED_STDERR_IGNORED_BINARIES
