Selected Phony Targets
----------------------
all:    Make everything there is to make.  This is the .DEFAULT_GOAL.

clean:  Remove some products.

cpio:   In the parent directory create a cpio(1) archive of the
        project source files whose name is time-stamped.

doc:    Build "synthslant.pdf" the Syntslant documentation.

gauge:  Build "synthslant-gauge.pdf" the Syntslant gauge and example
        file.

maintainer-clean: Remove every product file that can be rebuilt even
        if uncommon tools are necessary.

mostlyclean: Remove some more products than clean:.

pdf:    Build doc: and gauge:.

sty:    Only extract "synthslant.sty" from "synthslant.dtx".  This
        operation requires LaTeX (-> $(LATEX)) and nothing else.

tar:    In the parent directory create a tar(1) file of the project
        source files whose name is time-stamped.

tool-check: Check whether some of the required tools to build the
        project are available.


Selected Implicit Rules
-----------------------
%.dvi %.pdf: %.dtx
        Run LaTeX or pdfLaTeX (-> $(LATEX)) on dtx source until a
        fix-point is reached.

%.dvi %.pdf: %.tex
        Run LaTeX or pdfLaTeX (-> $(LATEX)) on tex file until a
        fix-point is reached.

%.mx.pdf: %.dvi
        Convert dvi to pdf via dvipdfmx (-> $(DVIPDFMX)).

%.ps: %.dvi
        Convert dvi to ps via dvips (-> $(DVIPS)).


Some Explicit Rules
-------------------
README.html:
        Convert "README.md" to html.  Requires markdown(1).

README: Convert "README.html" to plain text.  Requires w3m(1).
