-# Description
-
-These mkfiles can be used as is or as basis for your own mkfiles. Unlike
-standard files in `/mkfiles` these know how to handle `/opt` packages;
-able to build/run tests (both in host os and inside emu) and have other
-features (generation of INDEX files for your man pages, generation of man
-pages from text in asciidoc markup, etc.).
-
-
-# Install
-
-Make directory with these files available in /opt/mkfiles.
-
-Install system-wide:
-
-```
-# git clone https://github.com/powerman/inferno-opt-mkfiles.git $INFERNO_ROOT/opt/mkfiles
-```
-
-or in your home directory:
-
-```
-$ git clone https://github.com/powerman/inferno-opt-mkfiles.git $INFERNO_USER_HOME/opt/mkfiles
-$ emu
-; bind opt /opt
-```
-
-or locally for your project:
-
-```
-$ git clone https://github.com/powerman/inferno-opt-mkfiles.git $YOUR_PROJECT_DIR/opt/mkfiles
-$ emu
-; cd $YOUR_PROJECT_DIR_INSIDE_EMU
-; bind opt /opt
-```
-
-
-# Usage
-
-Start your new project using these mkfiles:
-
-```
-$ emu
-; mkdir newproject
-; cd newproject
-; cp /opt/mkfiles/mkconfig-example mkconfig
-; cp /opt/mkfiles/mkfile-example mkfile

-
-The `/opt/setup/cmd` will bind all commands provided by /opt packages into

-
-* https://github.com/powerman/inferno-opt-mkfiles
-* https://github.com/powerman/inferno-contrib-tap (only for tests)
-* https://github.com/powerman/inferno-contrib-logger (example dependency for
-  example command :))
-* http://asciidoc.org/ (converter from asciidoc markup to other formats)
-* https://github.com/powerman/asciidoc-9man-backend (asciidoc 9man backend
-  for converting into Inferno man pages)
-
-Actually all these dependencies are optional:
-
-* mkfiles project can be just copied to ./mkfiles/ subdir in your project
-  to avoid dependency on external project
-* tap module needed only for testing; you can use another modules, but
-  this one is cool because it allow you to run tests using `prove` command
-  in host os (standard testing tool for Perl)
-* logger is just an example dependency, nothing more
-* asciidoc needed only if you like to generate Inferno man pages from
-  simple .txt source
-
-
-# Usage
-
-Just copy `/opt/skel/` into your project's directory when you start new
-project.
-
-You can build your project using these commands both from host os and
-inside emu (except `prove`, which works only in host os):
-
-```
-mk all
-mk install
-
-mk test
-prove -r
-
-mk clean
-mk nuke
-```
-
-## Example
-
-When this project installed in `/opt/skel` and your /opt is correctly set
-(https://github.com/powerman/inferno-opt-setup) you can also:
-
-```
-$ emu
-; examplecmd
-Hello from ExampleLib->init()
-user.warn: Dec  6 05:04:40 examplecmd[158]: Hello from ExampleCmd->init()
-user.err: Dec  6 05:04:40 examplecmd[158]: Hello from ExampleCmd->init()
-; man examplecmd
