bash completion for teamocil

Question

I'm trying to define bash auto-completion for teamocil so that when I type teamocil <tab> it should complete with the file names in the folder ~/.teamocil/ without the file extensions. There's an example for zsh in the website:

compctl -g '~/.teamocil/*(:t:r)' teamocil

how can I use this in bash?

Edit: Influenced by michael_n 's answer I have come up with a one-liner:

complete -W "$(teamocil --list)" teamocil

Here's a generalized version of another completion script I have that does something similar. It assumes a generic hypothetical command "flist", using some directory of files defined by FLIST_DIR to complete the command (omitting options).

Modify the following for your program (teamocil), change the default dir from $HOME/flist to $HOME/.teamocil), define your own filters/transformations, etc; and then just source it (e.g., . ~/bin/completion/bash_completion_flist), optionally adding it to your existing list of bash completions.

# bash_completion_flist: 
#  for some hypothetical command called "flist",
#  generate completions using a directory of files

FLIST_DIR=${FLIST_DIR=:-"$HOME/flist"}

_flist_list_files() {
   ls $FLIST_DIR | sed 's/\..*//'
}

_flist() {
   local cur="${COMP_WORDS[COMP_CWORD]}"       
   COMPREPLY=()
   [[ ${cur} != -* ]] \
      && COMPREPLY=($(compgen -W "$(_flist_list_files)" -- ${cur}))
}

complete -o bashdefault -o default -o nospace -F _flist flist 2>/dev/null \
    || complete -o default -o nospace -F _flist flist

Notes:

it could be shorter, but this is more or less a template for longer, more complicated completions. (Functions are Good.)
the actual completion command (complete -o ...) is a bit of a hack to work across different versions of bash.
the suffix stripping is over-simplfied if there are "." in the filename, and is left as an exercise for the reader :-) There are multiple ways to do this (sed, awk, etc); the best is via bash-isms (base=${filename%.*}), but the easiest is arguably the simple sed with some assumptions about the filename format.

Bash implements similar idea but another way, so commands and files for zsh won't work in bash. But you may write your own rules for autocompletion. More info:
