usage_description="
Run a command for each Azure DevOps repo

All arguments become the command template

WARNING: do not run any command reading from standard input, otherwise it will consume the repo names and exit after the first iteration

\$AZURE_DEVOPS_ORGANIZATION / \$AZURE_DEVOPS_USER - the user or organization to iterate the repos on
\$AZURE_DEVOPS_PROJECT - the Azure DevOps project to iterate the repo on

The command template replaces the following for convenience in each iteration:

{organization}, {org} => the organization account being iterated
{username}, {user}    => the user account being iterated
{project}             => the project containing the repo
{name}                => the repo name without the user prefix
{repo}                => the repo name with the user prefix

eg.
    ${0##*/} echo user={user} project={project} name={name} repo={repo}
    ${0##*/} echo org={org}   project={project} name={name} repo={repo}
