description             Emulator for various architectures
long_description        QEMU is a generic and open source machine emulator. \
                        It can run OSes and programs made for one machine on a \
                        different machine. By using dynamic translation, it \
                        achieves very good performance.

# The qemu build system bugs out when using in-source-tree builds.
# During builds, files are generated in directories such as pc-bios, which are
# prerequites to the config-host.mak file. The latter gets generated during a
# configure run and can (in theory) be used for reconfiguring the package.
# Practically, this reconfiguration fails because it doesn't take special flags
# into account like LDFLAGS and the like, so we have to avoid reconfiguring
# qemu.
# Additionally, just "touch"ing the file doesn't work either, because it is a
# prerequisite of other generated file which will, likewise, be generated twice.
# Using out-of-source builds we can work around this issue in a pretty nice way.
