+# single-line-log
+
+Node.js module that keeps writing to the same line in the console (or a stream). Very useful when you write progress bars, or a status message during longer operations. Supports multilines.
+
+
+## Installation
+
+	npm install single-line-log
+
+
+## Usage
+
+``` js
+var log = require('single-line-log').stdout;
+// or pass any stream:
+// var log = require('single-line-log')(process.stdout);
+
+var read = 0;
+var size = fs.statSync('super-large-file').size;
+
+var rs = fs.createReadStream('super-large-file');
+rs.on('data', function(data) {
+	read += data.length;
+	var percentage = Math.floor(100*read/size);
+
+	// Keep writing to the same two lines in the console
+	log('Writing to super large file\n[' + percentage + '%]', read, 'bytes read');
+});
+```
+
+## .clear()
+
+Clears the log (i.e., writes a newline).
+
+``` js
+var log = require('single-line-log').stdout;
+
+log('Line 1');
+log.clear();
+log('Line 2');
+```
+
