1.60
----
- A bug in the variable substitutions has been removed (a '<'
character at the end of a file was just ignored).
- Cleaner installation and build procedure.
- A man page was written.

1.50
----
- Htmlc understands more SSI directives:
   - in addition to "last_modified", echo var also knows
     "date_local", "date_gmt", "user_name", "document_path_info",
     "document_name"
   - set (or define) defines a variable in the document
   - exec cmd="comm" launches the arbitrary Unix command named "comm"
     and inserts its result into the compiled document 
   - fsize gives the size of the document
   - flastmod to get the last modification date of the document
- The version of the Htmlc compiler is now available in the compilation
environment as $htmlc_version (or $htmlc_full_version to get also the
sub-version).

1.40
----
- Environment files syntax is almost compatible with Caml syntax:
     let ident = constant;;
     (* Simple remarks *)
  are properly understood.

- Flag -s meaning is generalized: output of htmlc -s filename.extension
  is still filename.html, but extension is no more limited to shtml
  (it can even be inexistant).

1.30
----
 - By default target files are read only to prevent editing of those
   instead of source files. Correlative -w flag to force htmlc to output
   a writable file.
 - Better environment file syntax:
       name = float
       name = bool
       name = int
       name = char
       name = string
       name = ident
   are accepted.
 - New -D option to bind a name to a value on the command line.

1.20 (Documents environment variables expansion)
----
 - Inside documents variables of the form $X, $(X), or ${X} are
   considered to be bound in the Htmlc's global environment hash table
   and expanded as their corresponding string associated value.
 - New -e argument to load environment files that set up Htmlc's global
   environment table. Environment files are list of lines
   that contain a variable name and an associated string (following Caml'
   lexical conventions).
 - New server side directive: the line
   <!--#include environment="filename"-->
   in a document loads environment file ``filename'' and enriches the
   global environment accordingly.
 - New -s compilation flag to expand .shtml files into .html files.

1.10 (User's environment variables expansion)
----
 - Throughout documents passed to htmlc, tags of the form <$X>
   are considered to reference the variable X in the user's
   gloabal environment: <$HOME> is thus replaced by the string
   representation of the user's HOME directory.
   (This expansion mechanism is disabled when including verbatim files).
