Libite aims tofill in thegaps missing inGLIBC/EGLIBC.(It does notaimo to becomeanother GLIBthough.) Onesuch gap inGLIBC is themissing _SAFEmacros insys/queue.h —highly rec
libtmt is theTiny MockTerminalLibrary. Itprovidesemulation of aclassic smarttext terminal,by maintainingan in-memoryscreen image.Sending textand commandsequences tolibtmt causesit to updatethis in-memoryimage, whichcan then beexamined andrenderedhowever theuser sees fit. libtmt issimilar inpurpose tolibtsm, butconsiderablysmaller (500lines versus6500 lines).libtmt is also,in thisauthor'shumble opinion,considerablyeasier to use.
