+Merge old source map and new source map in multi-transform flow
+
+
+# API
+
+```javascript
+var merge = require('merge-source-map')
+```
+
+
+## `merge(oldMap, newMap)`
+
+Merge old source map and new source map and return merged.
+If old or new source map value is falsy, return another one as it is.
+
+<dl>
+  <dt>
+    <code>oldMap</code> : <code>object|undefined</code>
+  </dt>
+  <dd>
+    old source map object
+  </dd>
+
+  <dt>
+    <code>newmap</code> : <code>object|undefined</code>
+  </dt>
+  <dd>
+    new source map object
+  </dd>
+</dl>
+
+
+# Example
+
+```javascript
+var esprima    = require('esprima'),
+    estraverse = require('estraverse'),
+    escodegen  = require('escodegen'),
+    convert    = require('convert-source-map'),
+    merge      = require('merge-source-map')
+
+const CODE = 'a = 1',
+      FILEPATH = 'a.js'
+
+// create AST of original code
+var ast = esprima.parse(CODE, {sourceType: 'module', loc: true})
+
+// transform AST of original code
+estraverse.replace(ast, {
+  enter: function(node, parent) { /* change AST */ },
+  leave: function(node, parent) { /* change AST */ }
+})
+
+// generate code and source map from transformed AST
+var gen = escodegen.generate(ast, {
+  sourceMap: FILEPATH,
+  sourceMapWithCode: true,
+  sourceContent: CODE
+})
+
+// merge old source map and new source map

+    mapComment = convert.fromObject(mergedMap).toComment()
+
+// attach merge source map to transformed code
+var transformed = gen.code + '\n' + mapComment
+
