ldbox is a lightweight virtualisation environment for crosscompilation.
It allows to transparently build and package software for Linux distributions
and architectures different than the one on a host system.
ldbox is lightweight and simple to use.
It requires no additional permissions besides ones a regular user
already has to setup build environment and run commands inside it.
ldbox doesn't use any system virtualisation and isolation capabilities
(not even chroot).
Instead, it preloads a shared library that modifies arguments to
many functions in glibc, the standard C library.
As a result, a program running under ldbox's control sees
a virtual filesystem view according to configurable rules.
Also, these rules control how new programs are started.
For example, a program for foreign architecture can be started inside an
emulator (like qemu),
and cross-compiler started instead of native compiler
for foreign architecture.
ldbox is a fork of Scratchbox 2 (sb2),
but has nothing to do with old Scratchbox that existed before sb2.
