Scilib-GEO
----------

Version 0.6 / 2018-12-01 (S. Gougeon)
------------------------
PORTAGE to Scilab 5.5 and 6
  . maxi => max
  . getf() => exec()
  . lstsize => size
  . eval => evstr
  . error(msg,err) => error(msg)
  . xset => set
  . isoview => replot + isoview
  . Heterogeneous strings "...'  replaced
  . shared internals:
    - sp3_parse_date() split from sp3_parse_file.sci
    - a7_svdata_createsv() split from a7_svdata_init.sci

BUGS FIXED:
* In unitVec() and xyz2asz(), compareVectors() was used instead of compare_vectors()
* %GEOlib_DIR was used without being defined.
* eph2xyz()
  - used macros/phys instead of macros/physgeo
  - ~isdef(kepler) instead of ~isdef("kepler")
* gmf() : beta and gamma were used as simple variables, overwritting defined primitives
* aequiKor(): delta was badly initialized.
* dat_leapseconds() had a syntax error and could not be compiled. This function
  is not called at all, but is documented. It is fixed and kept, for the record.
* plotWorldmap() never took the 2nd input argument into account.
* In pars_paramstr(), errors messages were about a7Core()
* tropKor_sm.sci defined tropKor() instead of tropKor_sm()

HELP PAGES: 
* "Used functions" section removed. Only one page over two had it. The list
  of functions was very poor, an rather arbitrary.
* plotWorldmap: image added.
* The page for get_tkblatt() was named get_tkblattnr and the example was about
  get_tkblattnr() that is not defined.
* dat_cal2j2k() : example could not run
* sp3_parse_file() and sp3c_parese_header(): The example needed a <screen>
  instead of a <programlisting>.
* atan2(): the example's result was not displayed. The xml:id was a7_atan2 instead of atan2.

DEMOS:
* readyuma() was called without being defined. alm_parse_yumafile() actually
  replaces it.
* plot_Erdrotation() can't run. It needs a "nutwinkel" function, that's not defined.
* plot_tropKor.sce was disabled by testing the existence of tropKor() instead of tropKor_sm().

OTHER IMPROVEMENTS:
* Errors messages => standard + english + now localizable
* New function getpath_geolib() (internal)
* This file CHANGES.txt created.
