Flag Description
dep Make DEP=true the default which enables support for {,R,P,B}DEPEND but requires roughly double disk and memory.
jumbo-build Compile faster and produce better binary. Recommended unless compiling on a quite memory-restricted system.
meson Build with meson instead of autotools. Faster but less compatible
required-use Make REQUIRED_USE=true the default which enables support for REQUIRED_USE but requires more disk and memory.
security This adds some checks which can prevent certain exploits if e.g. the eix code has a bug. If you use the hardened toolchain, using this flag does not increase security and can even lead to problems.
src-uri Make SRC_URI=true the default which enables support for SRC_URI but requires roughly double disk and memory.
strong-optimization Adds several more agressive CXXFLAGS/LDFLAGS for optimization like graphite (if available). May cause trouble with some buggy compiler versions. Absense of this USE flag does not strip user's *FLAGS
strong-security Add many checks to prevent exploits if eix code has a bug. This will slow down eix considerably. Use only if you are paranoid or have reasons to suspect a bug.
swap-remote Swap role of remote addresses in eix-remote, making the data from gpo.zugaina.org the first choice.
