RipMIME project is an email attachment extration tool.
RipMIME has been written as part of the (commercial) Xamime package, but because there was such a problem trying to attain a easy to use, openSource MIME decoder which the everyday person with some limited C skills could try and play with, we decided to release the MIME decoding components of Xamime as its own package which you are now seeing as "RipMIME".
RipMIME has a single sole pupose, to extract the attached files out of a MIME package (as say produced by programs such as AMaViS, Inflex and Xamime). RipMIME deliberately has no other operating purpose (if you find another use, then thats great).
It has been written (at this point) purely by Paul L Daniels and it is being released under a BSD style licence so that other commercial ventures may if they so desire use this product without the headaches normally associated with using GPL software.
Installation:
make
make install
Enhancements:
- A one-off boundary error in FFGET that caused segfaults for short files was fixed.
