"This section is optional.  If the intended user is not a programmer and does "
"not plan to do any debugging on the system software, the system size can be "
"decreased by about 2 GB by removing the debugging symbols from binaries and "
"libraries. This causes no inconvenience other than not being able to debug "
"the software fully anymore."

"unusable, so before running the <command>strip</command> commands, it is a "
"good idea to make a backup of the LFS system in its current state."
