A robust backup tool.
Conserve copies files, directories, and (on Unix) symlinks from a local source
tree, to a compressed archive directory, and retrieves them on demand.
The primary interface is the `conserve` command-line tool, and the key commands
are:
conserve init /backup/home.conserve
conserve backup /backup/home.conserve ~
conserve restore /backup/home.conserve /tmp/trial-restore
externcrate vergen;usevergen::*;fnmain(){letmut flags =OutputFns::empty();
flags.toggle(SEMVER);// Generate the version.rs file in the Cargo OUT_DIR.
assert!(vergen(flags).is_ok());}
