Building
========

Winexe makes use of Samba version 4.

Winexe can be built such that it is statically linked to Samba
libraries, resulting in an executable that is several megabytes in
size. The winexe binary is still dynamically linked to a number of
shared libraries such as libc.  

On some distributions winexe can be built such that it is linked to
Samba shared libraries, resulting in an executable less than 100
kilobytes in size.
