@ -1958,6 +1958,43 @@ lines beginning ``#`` are treated as comments::
bits of the configuration file (e.g., ``chmod 600 aria2.conf``), so
that other user cannot see the contents of the file.
The environment variables, such as ``${HOME}``, are expanded by shell.
This means that those variables used in configuration file are not
expanded. However, it is useful to ``${HOME}`` to refer user's home
directory in configuration file to specify file paths. Therefore,
aria2 expands ``${HOME}`` found in the following option values to
user's home directory:
* :option:`ca-certificate <--ca-certificate>`
* :option:`certificate <--certificate>`
* :option:`dht-file-path <--dht-file-path>`
* :option:`dht-file-path6 <--dht-file-path6>`
* :option:`dir <--dir>`
* :option:`input-file <--input-file>`
* :option:`load-cookies <--load-cookies>`
* :option:`log <--log>`
* :option:`metalink-file <--metalink-file>`
* :option:`netrc-path <--netrc-path>`
* :option:`on-bt-download-complete <--on-bt-download-complete>`
* :option:`on-download-complete <--on-download-complete>`
* :option:`on-download-error <--on-download-error>`
* :option:`on-download-start <--on-download-start>`
* :option:`on-download-stop <--on-download-stop>`
* :option:`on-download-pause <--on-download-pause>`
* :option:`out <--out>`
* :option:`private-key <--private-key>`
* :option:`rpc-certificate <--rpc-certificate>`
* :option:`rpc-private-key <--rpc-private-key>`
* :option:`save-cookies <--save-cookies>`
* :option:`save-session <--save-session>`
* :option:`server-stat-if <--server-stat-if>`
* :option:`server-stat-of <--server-stat-of>`
* :option:`torrent-file <--torrent-file>`
Note that this expansion occurs even if the above options are used in
the command-line. This means that expansion may occur 2 times: first,
shell and then aria2c.
