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 \fBnot\fR export them to the environment. .SH "FUNCTIONS" .TP die exit after emitting the supplied error message to the standard error stream. .TP usage die with the usage message. .TP 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. .TP 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). .TP cd_to_toplevel runs chdir to the toplevel of the working tree. .TP require_work_tree checks if the repository is a bare repository, and dies if so. Used by scripts that require working tree (e.g. checkout). .SH "AUTHOR" Written by Linus Torvalds .SH "DOCUMENTATION" Documentation by Junio C Hamano and the git\-list . .SH "GIT" Part of the \fBgit\fR(7) suite
