.SH NAME
.LP
\fBmakeflow_linker\fP - automatic dependency location for workflows

.SH SYNOPSIS
.LP
\FC\fBmakeflow_linker [options] <workflow_description>\fP\FT

.SH DESCRIPTION
.LP
\fBmakeflow_linker\fP is a tool for automatically determining dependencies of workflows. It accepts a workflow description, currently Makeflow syntax is required, and recursively determines the dependencies and produces a self-contained package. \fBmakeflow_linker\fP supports Python, Perl, and shared libraries.

.PP

\fBmakeflow_linker\fP finds dependencies by static analysis. \FCeval\FT and other dynamic code loading may obscure dependencies causing \fBmakeflow_linker\fP to miss some critical dependencies. Therefore it is recommended to avoid these techniques when desiging a workflow.

.SH OPTIONS
.LP
.LP

.SH EXIT STATUS
.LP
On success, returns zero. On failure (typically permission errors), returns non-zero.

.SH BUGS
.LP

.IP \(bu 4
The makeflow_linker does not check for naming collisions beyond the initial workflow inputs.
.IP \(bu 4
The makeflow_linker relies on regex parsing of files
