256color ZSH Plugin
This ZSH plugin enhances the terminal environment with 256 colors. It looks at
TERM environment variable and sees if there is respective
(n-)curses' termcap/terminfo descriptors for 256 colors available. The result
is a multicolor terminal, if available.
If the environment variable
$ZSH_256COLOR_DEBUG is set to any value when the
plugin loads, some debugging information is printed to stderr. This is useful
to find out which strategy was successful to set a 256 colors terminal.
