## Fwd: Factorial, p175

 pay attention.I prefer to get feedback in the list because when just code changes I change it in the french, english and spanish version of the book.When the text changes I do it in the french and english version.stefThat's very helpful! I, of course, have "notes":1. I'm impressed you got this working under Windows. When people say "cygwin" to me my eyes glaze over. 2. I don't think you gain anything by obfuscating "[hidden email]". ;-) -->git clone git [at] github [dot] com:bencoman/PharoByExample-english.git 3. You might want to point the user to any informational messages that appear at the end of the LaTeX install. It's a long install (as you note) so it's easy to miss the bits about adding to your various PATHs. On Wed, Oct 9, 2013 at 6:38 PM, wrote: blake wrote: ```Oh, it's huge.

 Stef--So you'd rather I keep offering feedback here than making change to the TeX?On Thu, Oct 10, 2013 at 10:23 PM, stephane ducasse wrote: pay attention.

 Stef, Would Blake supplying a diff of the TEX be sufficient?  I know you are too busy to track the English book directly, but I'd like to encourage Blake's enthusiasm to dig in at the source.  Also there may be other people for other languages (Japanese?) that follow the English source. Or on the finished PDF use something like http://lifehacker.com/5917106/diffpdf-finds-differences-between-pdf-files cheers -ben blake wrote: ```Stef-- So you'd rather I keep offering feedback here than making change to the TeX?
