## Overview ##

Simple Go library to read the minor planet center data files.

The go docs should be reasonable. If some thing doesn't seem to work please raise a bug.

The expected input files can be obtained here: http://www.minorplanetcenter.net/iau/MPCORB.html Either the gziped or unzipped files should work automatically, file type detection is done by simple file extension only.

## Example ##

```

package main

import (

	"flag"

	"fmt"

	"io"

	"log"

	"github.com/emilyselwood/gompcreader"

)

var inputfile = flag.String("in", "", "the minor planet center file to read")

func main() {

	flag.Parse()

	if *inputfile == "" {

		log.Fatal("No input file provided. Use the -in /path/to/file")

	}

	mpcReader, err := gompcreader.NewMpcReader(*inputfile)

	if err != nil {

		log.Fatal("error creating mpcReader ", err)

	}

	defer mpcReader.Close()

	var count int64

	result, err := mpcReader.ReadEntry()

	for err == nil {

		fmt.Printf("%s:%s\n", result.ID, result.ReadableDesignation)

		result, err = mpcReader.ReadEntry()

		count = count + 1

	}

	if err != nil && err != io.EOF {

		log.Fatal(fmt.Sprintf("error reading line %d\n", count), err)

	}

	fmt.Printf("read %d records\n", count)

}

```
