ooga How can I find out which source program a dependency is sourced from?
by running on terminal eopkg info <package-name>
you will get the information about what deps has this package and what are the reverse dependencies.
For example:
$ eopkg info poppler
Installed package:
Name : poppler, version: 22.07.0, release: 45
Summary : PDF Rendering Library
Description : PDF Rendering Library
Licenses : GPL-2.0-or-later
Component : desktop.library
Dependencies : zlib liblcms2 freetype2 libcairo libjpeg-turbo glibc libtiff fontconfig libstdc++ libnspr libpng
openjpeg glib2 curl libnss poppler-data
Distribution : Solus, Dist. Release: 1

Reverse Dependencies: graphviz libreoffice-common pdfarranger poppler-utils cups-filters
If you try to uninstall poppler
it will uninstall all "Reverse Dependencies", which in this case they are graphviz libreoffice-common pdfarranger poppler-utils cups-filters
