+  # Sourcetrail currently assumes one of the following two layouts for the
+  # placement of its files:
+  #
+  # AppImage Layout       Traditional Layout
+  # ├── bin/              ├── sourcetrail*
+  # │   └── sourcetrail*  └── data/
+  # └── share/
+  #     └── data/         sourcetrail: application executable
+  #                       data: contains assets exlusive to Sourcetrail
+  #
+  # The AppImage layout is the one currently used by the upstream project for
+  # packaging its Linux port. We can't use this layout as-is for nixpkgs,
+  # because Sourcetrail treating $out/share/data as its own might lead to
+  # conflicts with other packages when linked into a Nix profile.
+  #
+  # On the other hand, the traditional layout isn't used by the upstream project
+  # anymore so there's a risk that it might become unusable at any time in the
+  # future. Since it's hard to detect these problems at build time, it's not a
+  # good idea to use this layout for packaging in nixpkgs.
+  #
+  # Considering the problems with the above layouts, we go with the third
+  # option, a slight variation of the AppImage layout:
+  #
+  # nixpkgs
+  # ├── bin/
+  # │   └── sourcetrail* (wrapper for opt/sourcetrail/bin/sourcetrail)
+  # └── opt/sourcetrail/
