So when the user +says he's got a shiny new Arduino Uno, boards.txt knows that it has a +16MHz ATmega328 on it. It would be nice to access these data from the +command line too. + +In normal operation you simply specify the tag given to the board in +the boards.txt file, and optionally a field name. This program then +extracts the data to STDOUT. + +Most boards have names which are quite unwieldy, so we always refer to +a board by a tag, not its name. Strictly the tag is the bit before the +first dot in the boards.txt key. You can see a list of board tags and +names with the C<--boards> option. + +=head1 OPTIONS + +=over + +=item --boards_txt=[file] + +Specify the full path to the boards.txt file. + +=back + +The following options all disable the normal 'lookup' operation. + +=over + +=item --dump + +Dump the complete database in YAML format. + +=item ---boards + +Print a list of the tag and name of every board in the file. + +=item --find [query] <query> ... + +Find matching data. Strictly, return a list of values which match all +of the query terms, treating each term as a case-insensitive regexp. + +For example: + +=over + +=item --find 328 + +List data containing 328 (anywhere in the value). + +=item --find due + +List data containing 'due' (e.g. duemilanove). + +=item --find 328 due + +List data containing both 328 and due. + +=back + +=back + +=head1 BUGS AND LIMITATIONS + +There are no known bugs in this application. + +Please report problems to the author. + +Patches are welcome. + +=head1 AUTHOR + +Martin Oldfield, ex-atelier@mjo.tc + +Thanks to Mark Sproul who suggested doing something like this to me ages ago. + +=head1 LICENCE AND COPYRIGHT + +Copyright (c) 2011, Martin Oldfield.
