+# Readme for xzoom
+## Overview
+xzoom is a small screen magnification utility that stays focused on the same spot until you move its focus.
+
+## Upstream
+The original upstream is [https://webdiis.unizar.es/pub/unix/X11/xzoom-0.3.tgz](https://webdiis.unizar.es/pub/unix/X11/xzoom-0.3.tgz).
+Debian packages this on [salsa](https://salsa.debian.org/debian/xzoom).
+SUSE packages exist too: [1](https://build.opensuse.org/package/show/home:zhonghuaren/xzoom) [2](https://build.opensuse.org/package/show/home:Akoellh/xzoom)
+
+## Reason for being in stackrpms
+Fedora does not package any third-party loupe programs.
+
+## Alternatives
+I could not find my old non-free OS application i.Look, but it runs in Wine anyways.
+`kmag` sounds like a decent KDE alternative, but I didn't want to install 127MB of KDE just for a screen magnifier.
+GNOME Shell has some built-in viewer, but I do not use GNOME.
+
+## Dependencies
+Distro     | Packages
+---------- | ---------
+Fedora 32  | bash, glibc, libX11, libXext, libXt (these are all standard packages)
+
+## Differences from upstream
+Spec file is modified from the Suse ones to be more Fedora-like, based on [Fedora Packaging Guidelines](https://docs.fedoraproject.org/en-US/packaging-guidelines/).

+%description
+
+Like xmag, xzoom magnifies a section of the X display. Xzoom is different
+because it will continuously update the magnified area as the display
+changes. It is fast enough to enlarge small animations, for example.
+
+It can also mirror or rotate a part of the screen.
