+.SH "NAME"
+socket_wrapper \- A library passing all socket communications through unix sockets\&.

+.SH "DESCRIPTION"
+.sp
+socket_wrapper aims to help client/server software development teams willing to gain full functional test coverage\&. It makes possible to run several instances of the full software stack on the same machine and perform locally functional testing of complex network configurations\&.

+.SH "ENVIRONMENT VARIABLES"
+.PP
+\fBSOCKET_WRAPPER_DIR\fR
+.RS 4
+The user defines a directory where to put all the unix sockets using the envionment variable "SOCKET_WRAPPER_DIR=/path/to/socket_dir"\&. When a server opens a port or a client wants to connect, socket_wrapper will translate IP addresses to a special socket_wrapper name and look for the relevant unix socket in the SOCKET_WRAPPER_DIR\&.
+.RE
+.PP
+\fBSOCKET_WRAPPER_DEFAULT_IFACE\fR
+.RS 4
+Additionally, the default interface to be used by an application is defined with "SOCKET_WRAPPER_DEFAULT_IFACE=<ID>" where <ID> is between 2 and 254\&. This is analogous to use the IPv4 addresses "127\&.0\&.0\&.<ID>" or IPv6 addresses "fd00::5357:5f<IDx>" (where <IDx> is a hexadecimal presentation of <ID>)\&. You should always set the default interface\&. If you listen on INADDR_ANY then it will use the default interface to listen on\&.
+.RE
+.PP
+\fBSOCKET_WRAPPER_PCAP_FILE\fR
+.RS 4
+When debugging, it is often interesting to investigate the network traffic between the client and server within your application\&. If you define SOCKET_WRAPPER_PCAP_FILE=/path/to/file\&.pcap, socket_wrapper will dump all your network traffic to the specified file\&. After the test has been finished you\(cqre able to open the file for example with Wireshark\&.
+.RE
+.PP
+\fBSOCKET_WRAPPER_MTU\fR
+.RS 4
+With this variable you can change the MTU size\&. However we do not recomment to do that as the default size of 1500 byte is best for formatting PCAP files\&.
+.RE
+.sp
+The minimum value you can set is 512 and the maximum 32768\&.
+.PP
+\fBSOCKET_WRAPPER_DEBUGLEVEL\fR
+.RS 4
+If you need to see what is going on in socket_wrapper itself or try to find a bug, you can enable logging support in socket_wrapper if you built it with debug symbols\&.
