以下の内容のテキストファイルを file コマンドに食わせてみたら C++ source だって言われた．

First class is a travel class on some airliners intended to be more luxurious than business
class, premium economy, and economy class. On a passenger jetliner, first class usually refers
to a limited number (rarely more than 20) of seats or cabins toward the front of the aircraft 
which have more space, comfort, service, and privacy. Propeller airliners often had first 
class in the rear, away from the noise of the rotating propellor.

どうも class という単語が行頭にあると C++ source と判定されるらしい．なお，このテキストは Wikipedia の First class (aviation) の頭のところから持ってきて class の手前で改行してみたもの．
