[R] build CONTENTS or 00Index.html without installing whole package

[Jonathan Baron]

OK, one more for the records.  This script is now written so that it
uses Rscript instead of bash.  The last line still does not work.  I
don't know what make.packages.html requires, but apparently it
requires more than DESCRIPTION and 00Index.html in order to include a
package.  (The line about buildVignettes seems useless, so I commented
it out.)  The command line can include *.  So I use this after
download.packages(), with inst.R *.tar.gz.  (inst.R is what i call the
script.)

#!/usr/bin/Rscript --vanilla
# makes indexable help files for R packages, including pdf vignettes
# usage inst.R [files]
FILES <- commandArgs(TRUE)
print(FILES)
for (PKG in FILES)
  {
    system(paste("tar xfz",PKG))
    PK <- strsplit(PKG,"_")[[1]][1]
    print(PK)
    system(paste("mkdir -pv /usr/lib/R/library/",PK,"/html",sep=""))
# copy description (which contains version number)
    system(paste("cp ",PK,"/DESCRIPTION /usr/lib/R/library/",PK,sep=""))
# move vignettes if present
    system(paste("cp -r ",PK,"/inst/doc /usr/lib/R/library/",PK," >& /dev/null",sep=""))
#    buildVignettes(PK,paste("/usr/lib/R/library/",PK,sep=""))
# make html files
    system(paste("cd /usr/share/R/perl; ","perl build-help.pl --html /home/baron/",
                 PK," /usr/lib/R/library/","; cd /home/baron",sep=""))
# make indices
    tools:::.writePkgIndices(PK,paste("/usr/lib/R/library/",PK,sep=""))
    system(paste("rm -rf",PK))
  }
# try to build package list, doesn't work
# make.packages.html()
