 +The first two lines of this block are a bit of a mouth-full:
 +<code>
 +find $PKG -print0 | xargs -0 file | grep -e "executable" -e "shared object" | grep ELF \
 +  | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null || true
 +</code>
  
 +We can however pick out key words that are commands and that can help to make some sense of it.
 +ind" located at /usr/bin/find is a powerful utility  that has around 50 options. It basically does what it says on the can.With the -print0 option it separates what it finds with "\000"  - in a word NULL. 
  
- --- //[[wiki:user:captain_sensible|andy brookes]] 2019/12/28 19:28 (UTC)// +The "|" or pipe is used to pass the results of a command to another;in this case xargs which has a flag -0. This option  is for xargs to accept input that has /000 between them. ELF is is Executable & Linkable Format.

-//If you teach maths it doesn't stop you  embedding little English +To give succinct answer the two lines are removing debugging symbols and other unnecessary stuff to make the binaries smaller, faster and take up less memory.
  
 +<code>
 +mkdir -p $PKG/usr/doc/$PRGNAM-$VERSION
 +</code>
  
 +Here we are preparing a directory which will be called "latex2html-2019.2" located at  /usr/doc. This is so we an put relevant documentation into a directory relevantly called, so that a user can access documentation on the package.
 +The next lines put files such as  README.md into the /usr/doc/latex2html-2019.2 directory.
 +
 +<code>
 +cat $CWD/$PRGNAM.SlackBuild > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild
 +</code>
 +
 +That line goes back to the original directory that Latex2html.SlackBuild was run from ( i previously quoted Desktop) opens up the SlackBuild with "cat"  command and copies it to the documentation directory. 
 +Now before I submitted latex2html to slackbuilds obviously I did some testing and found that when the package was installed it had a fairly comprehensive output of what it could do just using: 
 +
 +<code>
 +$ latex2html --help
 +</code> 
 +
 +Also I had access to a comprehensive manual in pdf format; so in my case I did not write code for man pages. Instead I simply put a copy of "manual.pdf" into the /usr/doc/latex2html-2019.2 directory.
