[gnuastro-commits] master 170fb7d: Corrected comments in configuration files

[Mohammad Akhlaghi]

branch: master
commit 170fb7d1669a87a6fe09387f0396fa1e5cf2f33a
Author: Mohammad Akhlaghi <address@hidden>
Commit: Mohammad Akhlaghi <address@hidden>

    Corrected comments in configuration files
    
    The configuration file comments had not been updated since the updating of
    the option management system. So with this commit, it was re-written and
    copied/used for all the programs. The end of the top description of
    `--help' is also updated with the suggested command descriptions listed on
    the same line as the command.
    
    In ConvertType, I noticed that `p->quality' (which accepts a value between
    0 and 100) is being initialized with `UINT8_MAX' (because 0 is a valid
    value for it). But this value is only meant as a blank value (to identify
    if the option is actually given). So to be more clear, it is replaced with
    `GAL_BLANK_UINT8'.
