pstoedit
========

Today I needed to  edit a PDF file which was  created by something like
the AutoCAD  (just to add some  symbols for a presentation).  Having no
free tool to edit PDF file directly, I tried this way:

-----------------------------
pdf2ps file.pdf
pstoedit -f fix file.ps file.fig
-----------------------------

The I used th XFig (an interactive vector editor:

-----------------------------
xfig file.fig
-----------------------------

The XFig can export to PDF. 


And  it  worked. Of  course,  every  line  in  the original  file  was 
represented as a  independent entity in the XFig so  file was HUGE and 
its edit was little slow (I ran the XFig on a remote X11).
