comparison kconfig/lex.zconf.c_shipped @ 10:4d21d59f3206

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add menuconfig, plus some basic Config info, lots of which is just future plans for toysh. Nothing's currently _using_ this config info, but at least it's being generated now.
