#Dear Packager,

This document is a quick summary of all you need to know to package imv for your favourite operating system.

#Configuring imv

#1. Select window systems to support

Your options here are Wayland or X11, or both. By default both are included, with a separate binary for each being built. /usr/bin/imv will be a script that checks for a Wayland compositor before running the appropriate binary.

If you only care about one of these, you can specify to build only one of these by passing -D windows=wayland to meson, in which case only that binary shall be packaged without the need for a launcher script to select between the two.

Alternatively, you could provide separate packages for X11 and Wayland that act as alternatives to each other.

#2. Select backends to include

imv supports multiple "backends" in a plugin style architecture. Each backend provides support for different image formats using different underlying libraries. The ones that are right for your operating system depend on which formats you need support for, and your licensing requirements.

imv is published under the MIT license, but its backends may have different licensing requirements.

By default, the libraries available are detected and support for them is automatically enabled, but you can enable or disable specific ones by passing -D freeimage=enabled or -D libtiff=disabled. You can also make sure all the backends are enabled by passing -D auto_features=enabled.

#Building imv

Once your backends have been configured and you've confirmed the library each backend uses is installed, you can simply follow the Installation section of the README to build imv.

#Packaging imv

Package the resulting binary and man pages in your operating system's native package format.
