description: multiplatformal/distribution system  dumping and comparation

content: 
 xmlenv  ..................... main linux dump/show bash script
 compare-pkgs.xsl ............ template for XSLT comparation 
 pkglist-extra-installed.xsl . template for package lists comparations 

 example/base.xml ............ base system dump
 example/report-short.html ... short comparation report (to "current" system dump - ./pkgversions.xml)
 example/report-full.html .... full comparation report (to "current" system dump - ./pkgversions.xml)

 install.sh .............. executes installation to /urs/bin /usr/share/xmlenv/ directories

usage:
./xmlenv help .................... shows help
./xmlenv show .................... show the records
./xmlenv dump .................... create pkgversions.xml
./xmlenv compare-report .......... creates pkgversions.xml dump, compares it with base.xml and writes it to report.html
./xmlenv compare-installed-pkgs .. prints list of added packages from base state 
./xmlenv compare-removed-pkgs .... prints list of removed packages from base state 
./xmlenv check ................... checks system parameters given by commandline comma separated array
./xmlenv backup .................. dumps  pkgversions.xml to ~/.xmlenv/pkgversions_<timestamp>.xml

example1: generate default (short) comparation report:
xmlenv compare -b example/base.xml -o example/result-short.html 

example2: generate full comparation report:
xmlenv compare -v -b example/base.xml -o example/result-full.html --full
-v .............. script verbose output
-b <xml-file> ... dumped base xml file which we compare to
-or <html-file> . save report to somewhere else
--full .......... show in report 1.equal and 2.current unique(additional) packages

example3: dump with comment
xmlenv dump -c "before installing dev env"


example4: check installed packages
./xmlenv check pkglist gcc,gdb  .. returns 0
./xmlenv check pkglist gcc,gdb,not-existing .. returns 1

example5: remote backup dumping
ssh user@host 'bash /dev/stdin backup' < /usr/bin/xmlenv
scp -r user@host:.xmlenv .

example6: external comparation
./xmlenv compare-installed-pkgs -b ./first.xml -x ./second.xml -dd -r ./my-report.html

example7: state saving (to ~/.xmlenv/)
xmlenv backup -m "installed base image"

example8: package count from files
xmlenv show pkgcount -x pkgversions.xml
