 Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of this
 software is the integration with mail servers (attachment scanning). The
 package provides a flexible and scalable multi-threaded daemon in the
 clamav-daemon package, a commandline scanner in the clamav package, and a tool
 for automatic updating via Internet through the clamav-freshclam package. The
 programs are based on libclamav1, which you can use in your own software.
 .
 The package contains the needed headers and libraries for
 developing software using the libclamav interface.
 .
 This library can be used to develop virus scanner applications.
