Ever. +This documentation is meant for people who are studying the +Porcelain-ish scripts and/or are writing new ones. + +The `git-sh-setup` scriptlet is designed to be sourced (using +`.`) by other shell scripts to set up some variables pointing at +the normal git directories and a few helper shell functions. + +Before sourcing it, your script should set up a few variables; +`USAGE` (and `LONG_USAGE`, if any) is used to define message +given by `usage()` shell function. `SUBDIRECTORY_OK` can be set +if the script can run from a subdirectory of the working tree +(some commands do not). + +The scriptlet sets `GIT_DIR` and `GIT_OBJECT_DIRECTORY` shell +variables, but does *not* export them to the environment. + +FUNCTIONS +--------- + +die:: + exit after emitting the supplied error message to the + standard error stream. + +usage:: + die with the usage message. + +set_reflog_action:: + set the message that will be recorded to describe the + end-user action in the reflog, when the script updates a + ref. + +is_bare_repository:: + outputs `true` or `false` to the standard output stream + to indicate if the repository is a bare repository + (i.e. without an associated working tree). + +cd_to_toplevel:: + runs chdir to the toplevel of the working tree. + +require_work_tree:: + checks if the repository is a bare repository, and dies + if so.
