tcvt is an ANSI terminal emulator, that turns a $COLUMNS x $LINES terminal
into a $COLUMNS/n x $LINES*n terminal of n columns. It ships the two
commands tcvt and optcvt both of which are documented in the accompanying
manual page.
A fullscreen terminal on a full HD screen (1920x1080) can turn into four
columns of 80-159 characters for a single virtual terminal. The picture below
shows vi editing the code for tcvt on a full-HD screen.
The whole script for tcvt is visible on dual 30" monitors.
To run tcvt you need a Python 2.6, 2.7 or 3.3. Other than that only standard
Unix tools such as man, make, gzip, sed are needed.
tcvt is published under a 2-clause BSD license.
To install run make install optionally changing variables such as $DESTDIR
or $PREFIX.
