I am trying to generate docsets for Dash following these instructions: <http://kapeli.com/docsets>.
The problem is, that the script doesn't continue after the wget and doesn't appear to throw any errors. Everything works fine when I copy the script into the Terminal.

I'm using MacOS 10.8.4 and the default bash.

```
#!/usr/bin/env bash
set -e

mkdir -p $1.docset/Contents/Resources/Documents/

echo "THIS RUNS"
wget -rkp -l3 -np -nH --cut-dirs=1 --directory-prefix="./"$1".docset/Contents/Resources/Documents/" $2
echo "THIS DOES NOT RUN"

sed "s/NAME/$1/g" template > $1.docset/Contents/Info.plist
touch $1.docset/Contents/Resources/docSet.dsidx
# (script continues) 

```

I looked at other posts like [My shell script stops after exec](https://stackoverflow.com/questions/3877657/my-shell-script-stops-after-exec) but I'm not using `exec` here.

Why does the script exit?
