Directions for Mac OS X: 1) Make sure you have Apple X11 installed (search for X11 in you applications folder). You can download it from Apple web (http://www.apple.com/downloads/macosx/apple/macosx_updates/x11formacosx.html) or in your Mac OS X 10.4.x "Tiger" CDs/DVD. 2) Instal ActivePerl (www.activestate.com). Download from: http://www.apple.com/downloads/macosx/development_tools/activeperl.html or http://www.activestate.com/store/download.aspx?prdGUID=81fbce82-6bd5-49bc-a915-08d58c2648ca 3) Drop "Bio" folder on the folder-link with the illustrative name "Only after installing ActivePerl, drop "Bio" here"; you will be prompted for authenticate as administrative user. [by doing this, you are copying "Bio" folder from the original "/bmw/Perl/site/lib/" distribution to "/usr/local/ActivePerl-5.8/lib/", this is why this step MUST be done after installing ActivePerl] 4) The launching application (MacBmw) looks for X11 in the Applications folder, which is its default location. If it is not there, i.e. you have moved it to other folder like "Utilities", make an alias by dragging the X11 icon while pressing Option+Command keys and drop it in Applications. Then add the extension ".app" to the alias name: get the information panel (Command+i) for the alias and type ".app" (without quotation marks) next to "X11" in "name and extension" field. Press enter. 5) Finally, just copy the folder "bmw" to any place you want (e.g. Applications folder), just as any other Mac application. And that's all! Now you should be able to launch Bmw from the finder just by double-clicking "MacBmw" application, without knowing a single UNIX command!!! ------------------------------------------------------------------------- For advanced users information: The application MacBmw was build with Platypus 3.4 (http://sveinbjorn.org/platypus) based on this shell script: #!/bin/sh cd "$1/.." echo $PWD export PATH=/usr/local/ActivePerl-5.8/bin:$PATH /usr/bin/open /Applications/X11.app /usr/local/ActivePerl-5.8/bin/perl bmw.pl default.conf
