--- Comment #4 from Ben Woodard <woodard at redhat dot com> ---
While ELF files and their DWARF are not streamable reading abixml is serial=
ized
enough that it should be streamable. The real problem that this creates is =
when
preserving abixml files on storage in a compact format.

Say for example:
abidw foo.elf | gzip > foo.abixml.gz

Then later on you want to use it in a diff, then you run into a two step
process that requires extra temporary storage.

gunzip -c foo.abixml.gz > /tmp/foo.abixml
abidiff /tmp/foo.abixml
rm /tmp/foo.abixml

However if abidiff could handle stdin then it would be a much simpler proce=
ss:
gunzip -c foo.abixml.gz | abidiff - newfoo.elf
