Comment:
I'd be happy to submit a PR and maintain it, if I can get it to build.
I edited the template according to your suggestions:
```shell
# Template file for 'oilshell'
pkgname=oilshell
version=0.6.0
revision=1
wrksrc=oil-${version}
#archs="i686 x86_64"
build_style=configure
configure_args="--prefix=/usr --with-readline"
makedepends="readline-devel"
short_desc="Oil, a new unix shell."
maintainer=" <>"
license="Apache-2.0"
homepage="http://www.oilshell.org/"
distfiles="https://${pkgname}.org/download/oil-${version}.tar.xz"
checksum=141e3a5c1997a696d65747966978aaa38921d77e303aad9e77b4ab4aedab84b7

do_install() {
	vbin _bin/oil.ovm
 	# symlink osh, oshc to oil.ovm.
	cd ${DESTDIR}/usr/bin
	ln -s oil.ovm osh
	ln -s oil.ovm oshc 
	# for some reason osh expects itself to be in /usr/local/bin
	mkdir -p "${DESTDIR}/usr/local/bin"
	ln -s "${DESTDIR}/usr/bin/oil.ovm" "${DESTDIR}/usr/local/bin/osh"
}
```
I'm not sure if oilshell supports i686 or not. If the project doesn't mention anything about support, is it safe to assume there is no i686 support, or should I ask? For `configure_args`, by default it uses `--prefix=/usr`. Does adding a flag to that (`--with-readline`) overwrite the existing args? (in other words, do I need to add `--prefix=/usr`?)

It's failing to build with the message
```
=> oilshell-0.6.0_1: running do_build ...
strip -o _build/oil/ovm-opt.stripped _build/oil/ovm-opt  # What's the difference with debug symbols?
strip-wrapper: ignoring arguments: -o _build/oil/ovm-opt.stripped _build/oil/ovm-opt
# We need a relative path since it will be _bin/oil.ovm

```
Oilshell doesn't support out-of-tree builds, could that be causing this failure?
