# Script to put all wanted texlive collection containing map file fonts into one scm:
toinstall="collection-latexrecommended collection-latexextra collection-mathextra collection-metapost ulem collection-htmlxml"
# collection-fontsrecommended is depended on by collection-mathextra, -pictures by -latexextra.
# Using a tcz would require lots of symlinks upon loading it, and this wastes space! 
# scm is better, and we can adapt TDS through kpathsea configuration (see texlive.tcz's buildscript).
# TBD: Could be improved by further separating into a critical font scm (dvips, meta*, fonts, texmv-var) and a scm with the remaining bits.
# TBD: binaries here won't find a texmf.cnf
# loading only the latter would provide a reasonably complete environment with less TC extensions to download
