Installing the Style Packages

Optimally, the files svma.sty and svsa.sty should be placed in the same location as the rest of the style files; on UN$\star$X, that might be
[4]/usr/local/lib/tex/macros/svma.sty. If the user doesn't have the privileges to install system software, the environment variable TEXINPUTS may be set to look for style files wherever desired. For example, on UN$\star$X, the csh command
setenv TEXINPUTS ".:$HOME/lib:/usr/local/lib/tex/macros"
will cause TEX to look in the current directory, the user's private library directory, and the default system directory. svma.sty will be found if placed in any of these locations. Equivalent commands are available on most other operating systems.

Directly including the style file into your source, or using \input or \include will not work, because the style files contain special commands that are valid only when processed using documentstyle.
