Hi 


Platform details

Windows 7 64 bit SP1
Intel i7
16GB RAM


Tried to extract code from document "The mpssespi Package" with 

atangle.exe mpssespi.pdf


The following is the result.

C:\Users\uma01\Desktop\CODE\FTDI\TCL>atangle.exe mpssespi.pdf
no root chunk definition of, <<*>>=, was found
no root chunk definition of, <<*>>=, was found
    while executing
"error "no root chunk definition of, <<$root>>=, was found""
    (class "::atangle::tangler" method "tangle" line 12)
    invoked from within
"t tangle $ochan $root"
    (procedure "::atangle::main" line 33)
    invoked from within
"atangle main"
    (file "C:/Users/uma01/Desktop/CODE/FTDI/TCL/atangle.exe/lib/application/atan
gle.tcl" line 282)
    invoked from within
"source      $startup"
    (file "C:/Users/uma01/Desktop/CODE/FTDI/TCL/atangle.exe/main.tcl" line 38)

This not supposed to wotk on the PDF files

Atangle is intended to extract literate program chunks from the literate source and not the formatted PDF document.
