2012-09-13 wenzelm 2012-09-13 more liberal init_components: base dir may get created later when resolving missing components;

2012-08-17 wenzelm 2012-08-17 allow to provide external ISABELLE_IDENTIFIER for repository clone -- potentially relevant for isatest and mira; clarified spaces in file names -- ISABELLE_HOME is non-critical after abolishment of "make";
2012-08-14 wenzelm 2012-08-14 always retain doc-src (as regular component);
2012-08-08 wenzelm 2012-08-08 configure Admin as component, with its own lib/Tools;

2012-04-22 wenzelm 2012-04-22 USER_HOME settings variable points to cross-platform user home directory;
2012-04-17 wenzelm 2012-04-17 retain ISABELLE_HOME_WINDOWS which is useful for jEdit to fold file names symbolically, but without DOS expansion that causes problems with Cygwin/Posix roundtrip (cf. 5a7903ba2dac);
2012-04-16 wenzelm 2012-04-16 more precise handling of java failure, due to missing ISABELLE_JDK_HOME;

2011-02-13 wenzelm 2011-02-13 eliminated somewhat obsolete warning -- former "$HOME/Isabelle" vs. "$HOME/isabelle" no longer exist;
2011-02-13 wenzelm 2011-02-13 tuned;
2011-01-21 wenzelm 2011-01-21 JVM/Windows: more robust treatment of unicode in file names;

2011-01-19 wenzelm 2011-01-19 added librarypath: shared library convenience in bash, keeping LD_LIBRARY_PATH and DYLD_LIBRARY_PATH separate;
2011-01-11 wenzelm 2011-01-11 isabelle version -i;
2010-11-16 wenzelm 2010-11-16 init_component: require absolute path (when invoked by user scripts);

2010-01-04 wenzelm 2010-01-04 removed function "isabelle-process", keeping "isabelle" only -- functions within the process environment might get passed through a genuine /bin/sh, which does not allow non-identifiers here;
2010-01-04 wenzelm 2010-01-04 discontinued old ISABELLE and ISATOOL environment settings;
2010-01-04 wenzelm 2010-01-04 shell functions "isabelle-process" and "isabelle" refer to the proper executables statically -- for interactive use or sloppy bash scripts;
