David,

Thanks for this work. The diagrams are much easier to get an overview quickly.

It also is not completely accurate in what is marked as "environment 
variables" (in green). Not all of these symbolic names are actually variables 
that influence gnucash/gtk in any way. I only used these symbolic names to 
create a logical structure.

Of the ones you have marked as environment variables DOT_GNUCASH_DIR (for 
gnucash 2.6 and older), GNC_DATA_HOME (for gnucash 3.x and (as of gnucash 3.4) 
GNC_CONFIG_HOME will indeed be honored by gnucash.

But USER_DATA_HOME and USER_CONFIG_HOME are not interepreted in any way. And 
as far as I know GTK_DATA_HOME and GTK_CONFIG_HOME aren't either. On linux and 
MacOS you can manipulate the locations GTK uses by setting XDG_DATA_HOME and 
XDG_CONFIG_HOME. Gtk will access XDG_DATA_HOME/gtk-<version> and 
XDG_CONFIG_HOME/gtk-<version> respectively. 

XDG_DATA_HOME and XDG_CONFIG_HOME also affect gnucash in the same way though 
GNC_DATA_HOME and GNC_CONFIG_HOME take precedence if set.

HOME is indeed an environment variable, though I'd avoid changing this as it 
has a broad impact.

Geert
