AI Summary: This issue requests the creation of an R Markdown vignette to document the `wget_batch.sh` shell script. The vignette should explain the script's purpose, usage, required inputs, and configurable options, providing step-by-step instructions and troubleshooting tips. It needs to follow the style of an existing vignette (`afs-web-space.Rmd`) and be placed in the `vignettes/` folder.
