comparison src/libpam/handle.rs @ 166:2f5913131295

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Separate flag/action flags into flags and action. This also individualizes the type of flag for each PAM function, so that you can only call a function with the right flags and values.
