### Manifest
```bash
Usage:
merry manifest [flags]
Flags:
-e, --excludeSource is with exclude source file
-x, --extract extract manifest file from jar
-f, --filter string filter
-h, --help help for manifest
-m, --merge is merge package
-p, --path string path (default ".")
-s, --scan scan manifest file to graphviz
-v, --version show manifest version info of jar
```
examples:
```bash
merry manifest -s -x -f org.eclipse.equinox -p ~/sdk/equinox-SDK-4.15/plugins
```
### Generate Pom from jars
```bash
merry pom -p _fixtures/demo -m _fixtures/map/map.csv
```
### Call Graph by Manifest.MF
```bash
Flags:
-h, --help help for call
-m, --map string map file
-p, --path string path (default ".")
-s, --server with server
```
full steps:
```bash
merry manifest -s -p ~/sdk/apache-karaf-4.2.9/lib/boot -x
merry map -p ~/sdk/apache-karaf-4.2.9/lib/boot
merry call -p ~/sdk/apache-karaf-4.2.9/lib/boot -m map.csv
```
results:
show only one line with `strict`
```graphviz
strict digraph G {
a -> b [ label = "foo" ];
a -> b [ label = "bar" ];
}
```
#### Call Server
cmd: `merry call -s`
`merry` will read `manifest-map.json` and start to [http://localhost:3000](http://localhost:3000):
