# keys:
# * *max_nesting*: The maximum depth of nesting allowed in the parsed data
# structures. Disable depth checking with :max_nesting => false|nil|0,
# it defaults to 19.
# * *allow_nan*: If set to true, allow NaN, Infinity and -Infinity in
# defiance of RFC 4627 to be parsed by the Parser. This option defaults
# to false.
# * *symbolize_names*: If set to true, returns symbols for the names
# (keys) in a JSON object. Otherwise strings are returned, which is also
# the default.
# * *create_additions*: If set to false, the Parser doesn't create
# additions even if a matchin class and create_id was found. This option
# defaults to true.
# * *object_class*: Defaults to Hash
# * *array_class*: Defaults to Array
# * *quirks_mode*: Enables quirks_mode for parser, that is for example
# parsing single JSON values instead of documents is possible.

Gist (v#{Gist::VERSION}) lets you upload to https://gist.github.com/
The content to be uploaded can be passed as a list of files, if none are
specified STDIN will be read. The default filename for STDIN is "a.rb", and all
filenames can be overridden by repeating the "-f" flag. The most useful reason
to do this is to change the syntax highlighting.
If you'd like your gists to be associated with your GitHub account, so that you
can edit them and find them in future, first use `gist --login` to obtain an
Oauth2 access token. This is stored and used by gist in the future.
Private gists do not have guessable URLs and can be created with "-p", you can
also set the description at the top of the gist by passing "-d".
Anonymous gists are not associated with your GitHub account, they can be created
with "-a" even after you have used "gist --login".
If you would like to shorten the resulting gist URL, use the -s flag. This will
use GitHub's URL shortener, git.io. You can also use -R to get the link to the
raw gist.
To copy the resulting URL to your clipboard you can use the -c option, or to
just open it directly in your browser, use -o. Using the -e option will copy the
embeddable URL to the clipboard. You can add `alias gist='gist -c'` to your
shell's rc file to configure this behaviour by default.
Instead of creating a new gist, you can update an existing one by passing its ID
or URL with "-u". For this to work, you must be logged in, and have created the
original gist with the same GitHub account.
