25# Output a flatpak yaml sources list from an input yaml file specifying files at
26# base URLs. Files will be downloaded (and cached) to compute their checksums.
27# Usage: compose-url-sources input.yml output.yml
28# Dependencies: xonsh wget
30# Input should be formatted like the following example:
31# - name: My Assembly
32# baseurl: https://www.example.com/my-assembly/
33# dest: dependencies
34# files:
35# - My.Assembly.dll
36# - My.Assembly.dll.config
37# - name: Something else
38# baseurl: https://project.example.com/something-else/
39# dest: other-dependencies
40# files:
41# - deps.tar.xz
42# - icon.png
43# output.yml will then specify to download the following files:
44# https://www.example.com/my-assembly/My.Assembly.dll
45# https://www.example.com/my-assembly/My.Assembly.dll.config
46# https://project.example.com/something-else/deps.tar.xz
47# https://project.example.com/something-else/icon.png
