The patch below is my attempt at adding the flash-apex script and a
postinst script to the apex package. The diff is created between apex
version 1.5.13 and an imaginary version 1.5.14.
Would it be possible for you to incorporate these changes, along with
the changes in #451882, into your latest apex version, and upload the
new package?
Thanks.
Gordon
