 [Bulletin Board Systems]() (BBS) color codes to reconstruct them into HTML documents.

 ```go
-// open a text file
+// open the text file
 file, err := os.Open("pcboard.txt")
 if err != nil {

+// transform the MS-DOS text to Unicode
 decoder := charmap.CodePage437.NewDecoder()
 reader := transform.NewReader(file, decoder)
 
 // create the HTML equivalent of BBS color codes
-var htm bytes.Buffer
-match, err := bbs.HTML(&htm, reader)
+var buf bytes.Buffer
+cc, err := bbs.HTML(&buf, reader)
 if err != nil {
-    log.Fatal(err)

 }
 
 // fetch CSS
 var css bytes.Buffer

+if err := cc.CSS(&css); err != nil {
+    log.Print(err)

 }
 
-// print partial html and css
-fmt.Println(htm.String())
-fmt.Println(css.String())
+// print the partial html and css
+fmt.Fprintln(os.Stdout, css.String(), "\n", buf.String())

 ## Known codes
 
 ### PCBoard
 
 One of the most well-known applications for hosting a PC/MS-DOS BBS, PCBoard
-pioneered the file_id.diz file descriptor, as well as being endlessly expandable
-through software plugins known as PPEs. It developed the popular @X color code and
-@ control syntax.

 methods to implement color, and this library uses the Pipe Bar Color Codes.
 
 ### Telegard
 
 A PC/MS-DOS application became famous due to a source code leak or release by
-one of its authors back in an era when most developers were still highly
-secretive with their code. The source is incorporated into several other projects.

 ### WWIV
 
-A mainstay in the PC/MS-DOS BBS scene of the 1980s and early 1990s, it became well
-known for releasing its source code to registered users. It allowed them to expand
-the code to incorporate additional software such as games or utilities and port it
-to other platforms. The source is now Open Source and is still updated.
-Confusingly WWIV has three methods of colorizing text, 10 Pipe colors, two-digit
-pipe colors, and its original Heart Codes.

-later migrated to Windows. It was one of the few BBS applications that sold at
