+# Go's `text/template` package with newline elision
+
+This is a fork of Go 1.4's [text/template](http://golang.org/pkg/text/template/) package with one addition: a backslash immediately after a closing delimiter will delete all subsequent newlines until a non-newline.
+
+eg.
+
+```
+{{if true}}\
+hello
+{{end}}\
+```
+
+Will result in:
+
+```
+hello\n
+```
+
+Rather than:
+
+```
+\n
+hello\n
+\n
+```

+# Units - Helpful unit multipliers and functions for Go
+
+The goal of this package is to have functionality similar to the [time](http://golang.org/pkg/time/) package.
+
+It allows for code like this:
+
+```go
+n, err := ParseBase2Bytes("1KB")
+// n == 1024
+n = units.Mebibyte * 512
+```
