+VirtualXT is an IBM PC/XT (8088/V20) emulator that runs on modern
+hardware and operating systems. It is designed to be simple and
+lightweight yet still capable enough to run a large library of old
+applications and games.
+
+The virtualxt binary is built with an SDL2 frontend and meant to be run
+by a non-root user. The user will need to be added to the "users"
+group because the binary will open the provided boot images in read-
+write mode and "users" has write access to those images.
+
+For example:
+
+usermod -aG users bob
+
+The user's current working directory must be the same directory where
+the virtualxt binary is installed. Because of this requirement, the
+binary cannot be installed to a traditional location (e.g. /usr/bin/).
+
+A wrapper script, virtualxt-wrapper.sh, has been provided so that the
+user does not have to change to the directory where the virtualxt
+binary is installed. This wrapper script may be found in
+/usr/share/virtualxt/ and copied to a traditional location for
+storing binaries.
+
+For example:
+
+cp /usr/share/virtualxt/virtualxt-wrapper.sh \
+  /usr/bin/virtualxt-wrapper.sh
+chmod +x /usr/bin/virtualxt-wrapper.sh
+
+The wrapper script may then be executed as if the user's current
+working directory is actually the directory where the virtualxt binary
+is installed.
+
+For example:
+
+virtualxt-wrapper.sh -a boot/freedos.img

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
