About:
------------------------------------------------------------

This program will hopefully make it easier to compile
source code written in the go programming language.

A dependency graph is constructed from imports, this
is sorted with a topological sort to figure out if a legal
compile order is possible (loop check). The dependency
graph itself is used to compile packages, i.e. each
packages sits in its own go-routine and waits for its
dependencies to finish before it starts.



------------------------------------------------------------
Install:  [Linux/Unix/Mac/Windows]
------------------------------------------------------------

> go run mk.go install

This will compile + link the binary (gd) and move it
to $HOME/bin if it is present, if not it falls back to
$GOBIN.


> go run mk.go -help  to see all available targets/options



------------------------------------------------------------
Try it Out:
------------------------------------------------------------

You can try to compile the same source using the generated
executable: gd


$ gd src          # will compile source inside src
$ gd -p src       # will print dependency info gathered
$ gd -s src       # will print legal compile order
$ gd src -test    # will run unit-tests
$ gd src -fmt     # will format (gofmt) the source-code
$ gd src -o gd    # will compile and link executable

Philosophy (Babble?)
------------------------------------------------------------

Without a tool to figure out which order the source should
be compiled, Makefiles are usually the result. Makefiles
are static in nature, which make them a poor choice to handle
a dynamic problem like a changing source tree. They also make
flat structures quite common, since this usually simplifies
the Makefiles, but makes organisation far less intuitive than
a directory-tree package-structure.

Logo
------------------------------------------------------------

The logo was made with LaTeX and tikz, it's basically just
an upside down g filled with yellow..

=start LaTeX

\documentclass[12pt]{article}
