Currently flame graph generation requires a d3-flame-graph template to
be installed. Unfortunately this is hard to come by for things like
Debian [1].
If the template isn't installed then ask if it should be downloaded from
jsdelivr CDN. The downloaded HTML file is validated against an md5sum.
If the download fails, generate a minimal flame graph with the
javascript coming from links to jsdelivr CDN.
v3. Adds a warning message and quits before download in live mode.
v2. Change the warning to a prompt about downloading and add the
--allow-download command line flag. Add an md5sum check for the
downloaded HTML.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
