== Brief ==
Various programming notes and half-baked ideas. Maybe I'll formalize them for public consumption (when I get the time -- HA!)

== Cygwin Packages ==

Cygwin packages needed to run the software build tools:

* cvs
* cygutils
* file
* openssh
* openssl
* patch
* patchutils
* pdksh (or mksh)
* rxvt
* sharutils
* unzip
* vim
* zip

== cygwin_KSH Shortcut ==

Create a new shortcut on the desktop that targets <tt>c:\cygwin\bin\rxvt.exe</tt>. Then right click -> Properties to change Target to:
<pre>
C:\cygwin\bin\rxvt.exe -fn fixedsys -bg black -fg #[[C0FFC0]] +sb -g 126x47+0+0 -ls -title "cygwin_KSH" -e /usr/bin/ksh -l
</pre>

== secure shell ==
Secure shell (ssh) lets us interact with the repository server without prompting for a password each and every time (except for this first time.) Be careful with the spacing and funky characters as you type in the commands.

# Double click on the cygwin_KSH shortcut on your Desktop. You'll get a unix shell and a bunch of weird text (we'll deal with that later.)
# Type <tt>mkdir ~/.ssh</tt>
# Type <tt>scp cvsuser@CVSSERVER:.ssh/id_rsa ~/.ssh/id_rsa</tt>
# When prompted if you want to trust the host, enter <tt>yes</tt>.
# When prompted for a password, use the administrator password du jour (I won't document it since it will change)

== environment variables ==
Let's get rid of that weird text when you start cygwin_KSH, and initialize the environment. You need to copy some files from the repository server.

# Double click on the cygwin_KSH icon that you just copied. You'll get a unix shell and a bunch of weird text (again.)
# Type <tt>scp cvsuser@CVSSERVER:.profile ~/.profile</tt>
# Type <tt>scp cvsuser@CVSSERVER:etc.profile /etc/profile</tt>
# Type <tt>exit</tt>

If you're a geek like me and you really care, here's what $HOME/.profile looks like:
<pre>
export [[CVS_RSH]]=/usr/bin/ssh
export CVSROOT=:ext:cvsuser@CVSSERVER:/apc/repository
export BUILDTOOLS=$HOME/buildtools
export PATH=$PATH:$BUILDTOOLS/shell:/cygdrive/c/ibm/uv/bin
[ -d buildtools ] && cvs update –P –d buildtools
</pre>
You also copied in a modified <tt>/etc/profile</tt> that comments out the PS1 environment settings.

If you want to access the source code repository from the internet (e.g. you're programming in a hotel room in Greensboro, while munching on a bag of Dorito's in your underwear), you can change the ip-address in your $HOME/.profile from CVSSERVER to 66.20.XXX.XXX using <tt>vi</tt> or your favorite Windows editor.

== buildtools ==
The buildtools directory contains scripts and programs for building products. Typing in the <tt>cvs</tt> command below (a) verifies that all the components are properly installed, and (b) checks out a fresh copy of the utilities.

# Double click on cygwin_KSH
# Type <tt>cvs checkout buildtools</tt>
# Type <tt>exit</tt>

Now you're ready to build your own work area.
