Will *all* user have exactly the same fonts available ? If so then simply set
GS_LIB globally as well. If not, then individual accounts will require custom
cidfmaps in order to access the included fonts.

The *default* cidfmap is empty. That's because GS doesn't know what CIDfonts
you have available (and more importantly can't know which ones you may want to
include, or not).

Not precisely correct. Ghostscript only uses the one you modify if you tell it
where to look. If you do that then it uses the one you tell it about.

Built into the executable. Usually the entire executable will be loaded in
memory, but it may be a memory mapped disk file or similar.

Actually, it is. Each user can have a different set of customised fonts. One of
the purposes of cidfmap is to load TrueType fonts as CIDFonts. This is not
possible in a completely automated fashion, and so you must modify cidfmap to
include information which GS cannot extract itself.

Since you *must* edit the file manually, and its contents depend entirely on
which fonts are available to a given user (and their wishes as regards which
fonts should be made available) it makes perfect sense to require the user to
specify the location of the cidfmap file.

Then all your users will be limited to the precise set of fonts that were made
available when you edited the cidfmap. If one or more of those files is not
available to a particular user, and they try to use the font, they will get an
error.

Users will be unable to 'edit' the file you have loaded into the executable.
This means they could still supply a custom cidfmapp, but would have no idea
what was in the built-in version.


> Just have a question:

You cannot edit the ROM version. Simply edit the cidfmap and supply the
location using the -I switch.
