 # Pick one quadgram file (cld2_generated_quadchrome*.cc):
 #   0122_16 = 160K entries, smallest size, lowest accuracy (set cld2_table_size=0)
 #   0122_19 = 192K entries, medium size, medium accuracy (set cld2_table_size=1)
 #   0122_2  = 256K entries, largest size, highest accuracy (set cld2_table_size=2)
 #
 # For the CJK bigram file (cld_generated_cjk_delta_bi*.cc), always use
 # cld_generated_cjk_delta_bi_4.cc, as this is intended for use with Chromium.
 # The _32 variant of the file is intended for applications that use the full
 # 175-language version of CLD2.
