  Have anybody tried this ? I will try to embed it into lynx - ie I'l add or
 modify a file in the 'WWW/Library/Implementation' directory (and of course 
 something in 'src' will be added/modified). Here is my thoughts about how it 
 should be done:
 
 * I think it should be an alternative for currently availble source file
   screen - ie it won't be replaced. It will be invoked by '|' - ie 
   shift + '\' on unremapped PC keyboard. 
   
 * I'd like that module to have configuration settings somewhere (most
   probably in lynx.cfg accessible via file inclusion) - they will 
   be the following:
   -  Whether to remove excessive whites inside tags - between brackets and 
   tag attributes. Option name HTMLSRC_PACK_SPACES. 
   -  Whether to uppercase/lowercase/leave-as-is names of tags and names of 
   their attributes. Option name HTMLSRC_TAG_TRANSFORM, values are {0,1,2}
   (0 - leave-as-is, 1 - lowercase, 2 - uppercase).
   -  The program currently understands following lexems:
     comment, generalized angle brackets ( '<' , '>' , '</' ), tag name, 
     attribute name, attribute value, normal text ( this will be 
     inserted once). The option for each lexem is what combination of tags to 
     insert before and what after it.
    Two configuration parameters correspond to 1 lexem - each is a string - 
    a html tags. Configuration parameter corresponding to the starting this 
    lexem is suffixed with '_S', and corresponding to the end - '_E'. Here is 
    a table that shows correspondence between lexems and parameter names.     
    
    lexem                     Parameter string
    --------------------------------------------
    comment                   HTMLSRC_COM
    gen. angle brackets       HTMLSRC_BRACKET
    tag name                  HTMLSRC_TAGNAME
    attribute name            HTMLSRC_ATTRNAME
    attribute value           HTMLSRC_ATTRVAL
    normal text               HTMLSRC_NORMAL   

  Example: 
   HTMLSRC_COM_S:"<i>"
   HTMLSRC_COM_E:"</i>"
   #...

  Are there any opinions/suggestions?
  
PS:  I've enhanced/fixed the program I've sent before, so if anybody needs it, 
  mail me.
