Tarsnap is a secure, efficient online backup service: "Online backups for the truly paranoid". https://tarsnap.com

Normal users should only use the signed tarballs from tarsnap.com, but for experimental development, use:

autoreconf -i
./configure
make

Bash completion scripts: optional configure argument --with-bash-completion-dir[=DIR].

• If DIR is specified, it installs to that directory.

• If DIR is left blank, it attempts to use pkg-config and bash-completion >= 2.0 to determine where to put the bash completion scripts. If your system does not match those requirements, please specify DIR explicitly.
