documentation=documentation_locator may exist somewhere in the symbol and be made invisible. This attribute is used by Lepton to find relevant documentation for the symbol, or rather, the device or component associated with the symbol.
Attach this attribute just like the device attribute (see device attribute). This is a freestanding or floating attribute.
documentation_locator
is either the base filename of the
documentation, or it is the complete Internet URL (Uniform Resource
Locator). If it is the filename, an attempt will be made to search
for it in the current working directory, and then in the system and
user documentation directories, (usually
${prefix}/share/doc/lepton-eda and
~/.local/share/lepton-eda/doc/lepton-eda, check the output of
functions user-doc-dir
and sys-doc-dir
in the
(schematic doc)
module to make it sure).
Filename example:
documentation=sn74ls00.pdf
URL example:
documentation=http://www-s.ti.com/sc/ds/sn74ls00.pdf
