The OpenACC specification is developed by OpenACC organization members based on the feedback provided by OpenACC users. Proposed new features to the current specification are published in Technical Reports (TR) and made available for review by users.

Errata: For the 'copyout' clause (section 2.7.9), on line 1928, the modifier list should read 'always, alwaysout,' or 'zero.'
