you spelt Toilet wrong
Such a garbage product
I use toilet on every server where I have access to ~/.bashrc. It's helpful to have a rainbow-colored (--gay) banner to remind you which server you've connected to
toilet(1) General Commands Manual
NAME
TOIlet - display large colourful characters
SYNOPSIS
toilet [ -hkostvSW ] [ -d fontdirectory ]
[ -f fontfile ] [ -F filter ] [ -w outputwidth ]
[ -I infocode ] [ -E format ] [ message ]
DESCRIPTION
TOIlet prints text using large characters made of smaller characters. It is similar in many ways to FIGlet with additional features such as
Unicode handling, colour fonts, filters and various export formats.
USAGE
TOIlet either reads its input from the command line or from the standard input.
OPTIONS
-f, --font <name>
Use the given font instead of the default value. Fonts are .flf or .tlf files stored in the /usr/share/figlet directory. Fonts are
looked first in the font directory, then in the current directory. There is also a special built-in font called term that serves as
a fallback if no font is available.
-d, --directory <dir>
Specify the directory in which to look for fonts. The default value is set at build time and usually defaults to /usr/share/figlet.
-s, -S, -k, -W, -o
Select character composition rules. -S sets smushing (nicely merging glyphs), -k sets kerning (rendering subcharacters as close to
each other as possible), -W renders characters at their full width and -o sets overlapping (glyphs slightly overlap the previous
one). -s (default behaviour) uses the font's smushing information if any, otherwise forces overlapping, or does nothing if the
glyph only has one subcharacter.
-w, --width <width>
Set the output width. By default, TOIlet will wrap its output at 80 character columns.
-t, --termwidth
Set the output width to the terminal width.
-F, --filter <filters>
-F, --filter list
--gay, --metal
Specify a list of filters to be applied to the output. <filters> is a colon-separated list of filters such as crop:rotate:gay and
the special argument list outputs a list of available filters.
--gay and --metal are shortcuts to commonly used filters that are guaranteed to exist. Several -F flags can also be specified on the
command line, in which case filters will be applied in order of appearance.
-E, --export <format>
-E, --export list
--irc, --html
Specify the output format. By default, TOIlet will output UTF-8 text using ANSI colour codes suitable for most terminals such as
XTerm or rxvt. <format> is the name of the export format as recognised by libcaca. The special argument list outputs a list of
available export formats.
--irc and --html are shortcuts to commonly used export formats that are guaranteed to exist.
-h, --help
Display a short help message and exit.
-I, --infocode <code>
Print a FIGlet infocode. This flag is only here for FIGlet compatibility, see the figlet manpage for more information about it.
-v, --version
Output version information and exit.
EXAMPLES
toilet Hello World
toilet Hello | toilet
tail -f /var/log/messages | toilet -f term --gay
BUGS
FIGlet compatibility is not complete yet.

Maybe a microservice?
The ability to use pip under Jython 2.7.2 appears to be fundamentally broken by the servers requiring SNI. 
I’ve got standalone Jython installed and working, but calls to jython -m pip install for any library fail for ERROR: No matching distribution found for requests. Running again with max verbosity will show a snippet like this in the output:
Getting page https://pypi.org/simple/requests/

ERROR: Could not find a version that satisfies the requirement requests (from versions: none)
Cleaning up...
Removed build tracker '/tmp/pip-req-tracker-va_h9x'
ERROR: No matching distribution found for requests
Some quick searching around implies that Python pre-2.7.9 didn’t support SSL SNI, which implies Jython 2.7.2 probably doesn’t, and it looks like the pypi servers have been moved behind proxies using SNI.
Does anyone know a workaround for this issue?
There is a workaround. As suggested by toml this can be done by:
$ git clone https://github.com/psf/requests.git

That got me past the sticking point and automatically pulled/built/installed all the requirements in my local site-lib.
Directly copying the *.egg directories over to the site-lib of my Ignition server didn’t work, but thankfully all the libraries were cleanly implemented in subdirectories of the .egg directories. So I just copied those directories into site-lib on my Ignition server and everything appears to work so far.
Is there a better method to move/install things from site-lib/*.egg on one setup to another?

Good news everyone: If you are using pip and have been struggling, the Jython devs fixed the SNI issue in the main Jython code branch. I’ve updated the guide to reflect how to get it working using the bug fix. Take a look at the Using pip section of the guide.
I also made a few other improvements, adding an example for Flask (which is more popular than Bottle), and fleshing out the subprocess example a bit more to show passing arguments.
