Multiple Problems with font handling

[Oliver Mihatsch <oliver.mihatsch@mchp.siemens.de>]

I just installed the latest context beta and ran into multiple font problems 
with things that used to work before (I think so, at least:-)).

My setting:
   This is pdfeTeX, Version 3.14159-1.00a-pretest-20010806-2.1 (Web2C 7.3.3.1)
   ConTeXt  ver: 2001.12.20  fmt: 2002.2.22  int: english  mes: english

The problems:

1.  Hanging punctuation does not work.
     It simply does not "hang".
    Minimal example:

     \setupoutput[pdftex]
      \usetypescript[serif][hanging][pure]
      \setupalign [hanging]
   \definetypeface[modern][rm][serif][computer-modern][default][handling=pure]
      \showframe
      \starttext
         \modern\input tufte
      \stoptext

2.  \usetypescript[ptm]  does not reslove the fontname.
     The following minimal example

    \setupoutput[pdftex]
      \usetypescript[ptm]
      \setupbodyfont[ptm]
      \starttext
        \input tufte
      \stoptext

     makes kpathsea believe that it needs to create the tfm file  
     Times-Roman.tfm, which fails for obvious reasons.
      .....
      kpathsea: Running mktextfm  Times-Roman
      .... 
      ! I can't find file `Times-Roman.mf'.
      ...

3. Usage of  \usetypescriptfile [type-buy] results in an "Undefined control 
sequence."

   ! Undefined control sequence.
<argument> \processcommalist [\typescriptencoding 
                                                  -itc-officina]

     It seems that the multiply occuring  \typescriptencoding needs to be 
replaced by  \typescripttwo or \typescriptthree depending on the context.

I do not know whether this is supposed to work.
Are these bugs or is it simply wrong usage?
