there is xlint from the xtool package that you can use to get your pkg template checked for common errors

```
srcpkgs/vpm/template:6: short_desc should not start with an article
srcpkgs/vpm/template:7: maintainer needs email address
srcpkgs/vpm/template:14: indent with tabs
srcpkgs/vpm/template:17: Last line is empty
```
