| This directory is workaround to avoid build error of GYP. | |
| parser.y was located at rewriter/calculator/, but it | |
| caused build error of calclator.gyp:calculator. GNU make tried to call yacc | |
| to process parser.y, though there was no rule about parser.y in gyp files. | |
| This error can be avoided by moving parser.y to some directory other than that | |
| of parser.c, so I moved it to this directory. | |
