14.8.2.7 ‘:tangle’
..................
The ‘:tangle’ header argument specifies whether or not the code block
should be included in tangled extraction of source code files.
• ‘tangle’ The code block is exported to a source code file named
after the full path (including the directory) and file name (w/o
extension) of the Org mode file. E.g., ‘:tangle yes’.
• ‘no’ The default. The code block is not exported to a source code
file. E.g., ‘:tangle no’.
• other Any other string passed to the ‘:tangle’ header argument is
interpreted as a path (directory and file name relative to the
directory of the Org mode file) to which the block will be
exported. E.g., ‘:tangle path’.
