annex.jobs=cpus etc
Added the ability to run one job per CPU (core), by setting annex.jobs=cpus,
or using option --jobs=cpus or -Jcpus.

Built with future expansion in mind, including not defaulting matching on
Concurrency so more constructors can later be added, and using "cpu"
instead of "0".

# NAME
git-annex addurl - add urls to annex
# SYNOPSIS
git annex addurl `[url ...]`
# DESCRIPTION
Downloads each url to its own file, which is added to the annex.
When `youtube-dl` is installed, it can be used to check for a video
embedded in a web page at the url, and that is added to the annex instead.
(However, this is disabled by default as it can be a security risk.
See the documentation of annex.security.allowed-http-addresses
in [[git-annex]](1) for details.)
Urls to torrent files (including magnet links) will cause the content of
the torrent to be downloaded, using `aria2c`.
Normally the filename is based on the full url, so will look like
"www.example.com_dir_subdir_bigfile". In some cases, addurl is able to
come up with a better filename based on other information. Options can also
be used to get better filenames.
# OPTIONS
* `--fast`
Avoid immediately downloading the url. The url is still checked
(via HEAD) to verify that it exists, and to get its size if possible.
* `--relaxed`
Don't immediately download the url, and avoid storing the size of the
url's content. This makes git-annex accept whatever content is there
at a future point.
This is the fastest option, but it still has to access the network
to check if the url contains embedded media. When adding large numbers
of urls, using `--relaxed --raw` is much faster.
* `--raw`
Prevent special handling of urls by youtube-dl, bittorrent, and other
special remotes. This will for example, make addurl
download the .torrent file and not the contents it points to.
* `--file=name`
Use with a filename that does not yet exist to add a new file
with the specified name and the content downloaded from the url.
If the file already exists, addurl will record that it can be downloaded
from the specified url(s).
* `--pathdepth=N`
Rather than basing the filename on the whole url, this causes a path to
be constructed, starting at the specified depth within the path of the
url.
For example, adding the url http://www.example.com/dir/subdir/bigfile
with `--pathdepth=1` will use "dir/subdir/bigfile",
while `--pathdepth=3` will use "bigfile".
It can also be negative; `--pathdepth=-2` will use the last
two parts of the url.
* `--prefix=foo` `--suffix=bar`
Use to adjust the filenames that are created by addurl. For example,
`--suffix=.mp3` can be used to add an extension to the file.
* `--jobs=N` `-JN`
Enables parallel downloads when multiple urls are being added.
For example: `-J4`
Setting this to "cpus" will run one job per CPU core.
* `--batch`
Enables batch mode, in which lines containing urls to add are read from
stdin.
* `-z`
Makes the `--batch` input be delimited by nulls instead of the usual
newlines.
* `--with-files`
When batch mode is enabled, makes it parse lines of the form: "$url $file"
That adds the specified url to the specified file, downloading its
content if the file does not yet exist; the same as
`git annex addurl $url --file $file`
* `--json`
Enable JSON output. This is intended to be parsed by programs that use
git-annex. Each line of output is a JSON object.
* `--json-progress`
Include progress objects in JSON output.
* `--json-error-messages`
Messages that would normally be output to standard error are included in
the json instead.
# CAVEATS
If annex.largefiles is configured, and does not match a file, `git annex
addurl` will add the non-large file directly to the git repository,
instead of to the annex. However, this is not done when --fast or --relaxed
is used.
