+# go-sendxmpp
+
+## about
+
+A little tool to send messages to an XMPP contact or MUC inspired by (but not as powerful as)
+[sendxmpp](https://sendxmpp.hostname.sk/).
+
+## requirements
+
+* [go](https://golang.org/)
+
+## installation
+
+If you have *[GOPATH](https://github.com/golang/go/wiki/SettingGOPATH)*
+set just run this commands:
+
+```bash
+$ go get salsa.debian.org/mdosch-guest/go-sendxmpp
+$ go install salsa.debian.org/mdosch-guest/go-sendxmpp
+```
+
+You will find the binary in `$GOPATH/bin` or, if set, `$GOBIN`.
+
+## usage
+
+The account details for logging into your XMPP account and at least `contact`
+or `muc` must be specified.
+
+If `-message` is not specified you can either pipe a programs output to
+`go-sendxmpp` or write in your terminal (put ^D in a new line to finish).
+
+If `-port` is not set, the standard port *5222* is used.
+
+```bash
+Usage of ./go-sendxmpp:
+  -contact string
+        Recipient of the message. (default "alice@example.com")
+  -message string
+        The message you want to send. (default "Hello World!")
+  -muc string
+        MUC to send the message to. (default "offtopic@conference.example.com")
+  -muc-nick string
+        The nickname the bot uses in the MUC. (default "go-sendxmpp")
+  -pass string
+        Password for XMPP account. (default "ChangeThis!")
+  -port string
+        XMPP server port. (default "5222")
+  -server string
+        XMPP server address. (default "example.com")
+  -user string
+        Username for XMPP account. (default "bob@example.com")
+```
+
+### examples
+
+```bash
+inxi -F | ./go-sendxmpp -pass 'ChangeThis!' -port '5222' -server 'example.com' -user 'bob@example.com' -muc 'test@conference.example.com'
+```
+
+```bash
+./go-sendxmpp -pass 'ChangeThis!' -port '5222' -server 'example.com' -user 'bob@example.com' -muc 'test@conference.example.com' -message 'Hello World!'
+```
