This can happen, for example, because of the linking errors or +# because the version (and therefore the name) of one of the shared libraries +# has changed as a result of updating another part of a toolchain (for +# instance, updating bpkg can trigger an update of libbpkg and this could make +# bdep, which also depends on libbpkg, no longer runnable). +# +# There are several mechanisms for recovering from such situations. If the +# build system is functional, it itself and the rest of the toolchain can +# always be update by first disabling the auto-synchronization hooks (which +# invoke bdep and bpkg). For example, the following commands should get the +# toolchain back into the fully-functional state: +# +# BDEP_SYNC=0 b build2/build2/ bpkg/bpkg/ bdep/bdep/ +# b build2/build2/ bpkg/bpkg/ bdep/bdep/ +# +# If the build system itself is not functional, it can always be rebuilt using +# the bootstrapped build system (b-boot).
