comparison src/_doc.rs @ 116:a12706e42c9d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Logging, macros, and building: - Changes logging API to accept the `Location` of the log statement. Fixes OpenPAM implementation. - Stops publicly exporting doc macros. - Uses dlopen to detect the PAM library rather than header jankery.
