amt_info - Displays the license, technical requirements, authors, and status of a file

Program code:

 function varargout = amt_info(varargin)
%amt_info Displays the license, technical requirements, authors, and status of a file
%   Usage: amt_info('modelname')
%          amt_info('once')
%
%   Input parameters:
%      'modelname'    : search pattern (typically the name of the first
%                       author) associated to a model. 
%      'once'         : can only be called from within a model or modelstage.
%                       Displays the license, technical requirements, and
%                       authors of that model once, the first time a model 
%                       is run within an AMT session.
%
%   Examples:
%      amt_info('takanen'): lists the paths to all models and modelstages in
%                           the AMT associated to publications with first 
%                           author Takanen
%      amt_info('culling2004'): lists the license, technical requirements,
%                               and authors of the model 'culling2004'
%
%   If not specified, the license will always be GPLv3.
