+  This file contains  a precompiled CCMap for a class of Unicode
+  characters (blank_glyph) to be identified quickly by Mozilla. 
+  It was generated  by  ccmapbin.pl which you can find  under

+
+  Enumerated below are characters included in the precompiled CCMap
+  which is human-readable but not so human-friendly.  If you 
+  needs to modify the list of characters belonging to "blank_glyph",
+  you have to make a new file (with the name of your choice)
+  listing characters (one character per line) you want to put 
+  into "blank_glyph" in the format
+
+         0xuuuu // comment
+
+  In addition, the input file can have the following optional lines that
+  read
+
+      CLASS::blank_glyph
+      DESCRIPTION:: description of a character class 
+      FILE:: mozilla source file to include output files
+      
+
+  Then, run the following in the current directory.
+
+    perl ccmapbin.pl input_file [blank_glyph]

+  This file contains  a precompiled CCMap for a class of Unicode
+  characters (dbyte_special_chars) to be identified quickly by Mozilla. 
+  It was generated  by  ccmapbin.pl which you can find  under 
+  mozilla/intl/unicharutil/tools.
+
+  Enumerated below are characters included in the precompiled CCMap
+  which is human-readable but not so human-friendly.  If you 
+  needs to modify the list of characters belonging to "dbyte_special_chars",
+  you have to make a new file (with the name of your choice)
+  listing characters (one character per line) you want to put 
+  into "dbyte_special_chars" in the format
+
+         0xuuuu // comment
+
+  In addition, the input file can have the following optional lines that
+  read
+
+      CLASS::dbyte_special_chars
+      DESCRIPTION:: description of a character class 
+      FILE:: mozilla source file to include output files
+      
+
+  Then, run the following in the current directory.
+
+    perl ccmapbin.pl input_file [dbyte_special_chars] 
+
+  which will generate dbyte_special_chars.ccmap.

+ /*========================================================
+  This file contains  a precompiled CCMap for a class of Unicode
+  characters (punct_marks) to be identified quickly by Mozilla. 
+  It was generated  by  ccmapbin.pl which you can find  under 
+  mozilla/intl/unicharutil/tools.
+
+  Enumerated below are characters included in the precompiled CCMap
+  which is human-readable but not so human-friendly.  If you 
+  needs to modify the list of characters belonging to "punct_marks",
+  you have to make a new file (with the name of your choice)
+  listing characters (one character per line) you want to put 
+  into "punct_marks" in the format
+
+         0xuuuu // comment
+
+  In addition, the input file can have the following optional lines that
+  read
+
+      CLASS::punct_marks
+      DESCRIPTION:: description of a character class 
+      FILE:: mozilla source file to include output files
+      
+
+  Then, run the following in the current directory.
+
+    perl ccmapbin.pl input_file [punct_marks] 
+
+  which will generate punct_marks.ccmap.
