+[![Go Report Card](https://goreportcard.com/badge/github.com/leighmcculloch/embedfiles)](https://goreportcard.com/report/github.com/leighmcculloch/embedfiles)
+
+Embedfiles is a tool for embedding files into Go code.
+
+Files are stored in a map of filenames to file data.
+
+## Install
+
+### Source
+
+```
+go get 4d63.com/embedfiles
+```
+
+## Usage
+
+```
+$ embedfiles
+Embedfiles embeds files into a map in a go file.
+
+Usage:
+
+  embedfiles -out=files.go -pkg=main <paths>
+
+Flags:
+
+  -file-names-var string
+        name of the generated file names slice (default "fileNames")
+  -files-var string
+        name of the generated files slice (default "files")
+  -out file
+        output go file (default "files.go")
+  -pkg package
+        package name of the go file (default "main")
+  -verbose
+```
+
+## Example
+
+Given files:
+```
+$ echo "hello world" > file1
+$ mkdir morefiles
+$ echo "who are you?" > morefiles/file2
+```
+
+Embed with `embedfiles`:
+```
+$ embedfiles file1 morefiles
+```
+
+A new file `files.go` is created:
+```
+$ cat files.go
+// Generated by 4d63.com/embedfiles.
+
+package main
+
+var fileNames = []string{
+        "file1", "morefiles/file2",
+}
+
+var files = map[string][]byte{
+
+        "file1": []byte{
+                31, 139, 8, 0, 0, 0, 0, 0, 2, 255, 202, 72, 205, 201, 201, 87, 40, 207, 47, 202, 73, 225, 2, 4, 0, 0, 255, 255, 45, 59, 8, 175, 12, 0, 0, 0,
+        },
+
+        "morefiles/file2": []byte{
+                31, 139, 8, 0, 0, 0, 0, 0, 2, 255, 42, 207, 200, 87, 72, 44, 74, 85, 168, 204, 47, 181, 231, 2, 4, 0, 0, 255, 255, 138, 46, 37, 108, 13, 0, 0, 0,
+        },
