The function component-library defines a directory containing
symbol files as a component resource. You should use it as
follows:
(component-library path)
or
(component-library path name)
path is a path to the directory you want to add as a component
resource. Environment variables in path are expanded. Using
this function is convenient if you want each of your library to have a
unique descriptive name. It can be specified with the second argument
name. The name is optional, if it is omitted, path is
used instead. The name will be displayed in the ‘Select
component’ window of lepton-schematic. Obviously, it is
useless for CLI Lepton tools.
