comparison dep/toml11/toml/macros.hpp @ 318:3b355fa948c7

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
config: use TOML instead of INI unfortunately, INI is not enough, and causes some paths including semicolons to break with our current storage of the library folders. so, I decided to switch to TOML which does support real arrays...
