Hi,

I'm trying to use 'pdfjam' from texlive-tiny.

When I run it, I get a message that 'pdfpages' wasn't installed, so I 
add texlive-latex-pdfpages to the environemnts.  Likewise, I add 
texlive-latex-eso-pic.  Then it says that everyshi isn't found, so I try 
to add that as well.

According to the second search result of "guix search everyshi", 
everyshi can be found in texlive-latex-ms:

> name: texlive-latex-ms
> version: 59745

> synopsis: Various LATEX packages by Martin Schröder  
> description: A bundle of LATEX packages by Martin Schröder; the collection comprises:
> + 
> +    * `count1to', make use of fixed TEX counters;
> + 
> +    * `everysel', set commands to execute every time a font is selected;
> + 
> +    * `everyshi', set commands to execute whenever a page is shipped out;
> + 
> +    * `multitoc', typeset the table of contents in multiple columns;
> + 
> +    * `prelim2e', mark typeset pages as preliminary; and
> + 
> +    * `ragged2e', typeset ragged text and allow hyphenation.
> relevance: 2

However, when I add this to the environment, I get the same 'not 
installed' error message.  Going by the contents "guix build 
texlive-latex-ms", it only contains 'count1to' and 'multitoc', so the 
other items should be removed from the list, or the other LaTeX packages 
must be made part of this Guix package.

(Also, standard capitalisation (*) is LaTeX and TeX, not LATEX or TEX.)

Then, I try the first search result: texlive-everyshi, which appears to 
work.  (I have to add 'texlive-pdflscape', 'texlive-generic-iftex' too, 
but that's another matter.).

Maxime.
